A water circulating pump is used in the boiler to circulate water inside the boiler. This pump is driven by the steam turbine which uses steam of boiler. It is used in power plant industries to generate electricity.\r\n\r\nPrinciple Of Lamont Boiler:\r\n\r\nThis boiler works on basic principle of forced convection. If the water is circulate by a pump inside the tube, the heat transfer rate from gas to the water is increases. It is the basic principle of it.\r\n\r\nConstruction Of Lamont Boiler:\r\n\r\nThis boiler is the first force circulation boiler. This boiler consist various part which are as follow.\r\n\r\nEconomizer:\r\nEconomizer use to preheat the water by using remaining heat of the combustion gases. It increases the boiler efficiency. The feed water first supplied to the economizer before entering to the boiler.\r\n\r\nCentrifugal pump:\r\nThe Lamont boiler is a force convection boiler. So a centrifugal pump is used to circulate water inside the boiler. This pump is driven by a steam turbine. The steam for the turbine is taken by the boiler.\r\n\r\nEvaporator tube:\r\nThe evaporator tube or can say water tubes are situated at furnace wall which increase the heating surface of boiler. This is also at the up side and down side of the furnace and other equipment. The main function of these tubes to evaporate water into steam. \u00a0This also cools down the furnace wall.\r\n\r\nGrate:\r\nThe space in the furnace where the fuel is burn is called grate. It is bottom side of furnace.\r\n\r\nFurnace:\r\nIn the Lamont boiler vertical furnace is used. The main function of Furnace is to burn the fuel.\r\n\r\nSuper heater:\r\nThe steam generated by the evaporator tube is saturated steam. If it directly used in steam turbine can cause the corrosion. So the saturated steam sends to the super heater where it can increase the temperature of steam.\r\n\r\nWater steam separator drum:\r\nThe steam separator is situated outside from the boiler. The mixture of water and steam from the evaporator tube send to the steam separator where it separate the steam and send it to super heater. The remaining water again sends to the economizer.\r\n\r\nAir preheater:\r\nIt\u2019s main function to preheat air before entering into furnace.\r\n\r\n\r\n\r\nConstructions And Working Of Lamont Boiler | Application\r\n\r\n\u00a0\r\n\r\nWorking:\r\nLamont boiler is a forced circulation, internally fired water tube boiler. The fuel is burn inside the boiler and the water is circulating by a centrifugal pump through evaporator tubes. The working of this boiler is as follow.\r\n\r\nA feed pump forces the water into the economizer where the temperature of water increases. This water forced into the evaporator tube by using a centrifugal pump driven by steam turbine. Water passes 10 - 15 times into the evaporator tube. The mixture of saturated steam and water is formed inside the tube.\r\n\r\nThis mixture sends to the steam separator drum which is outside the boiler. Steam from the separator sends to the super heater, where the saturated steam converts into superheated steam. The water again sends to the economizer where it again passes by the evaporator tubes.\r\n\r\nThe air from the air preheater enter into the furnace where fuel burn. The flue gases first heat the evaporator tube then passes by the super heater. These gases from the super heater again use to preheat the air into air preheater before exhaust into atmosphere.\r\n\r\nThis working pressure of this boiler is above 170 bar and have the steam generation capacity of about 50000 kg\/hour at temperature 773 K .\r\n\r\nAdvantages:\r\n\r\n1. It can high pressure boiler.\r\n2. It is flexible in design.\r\n3. This boiler can reassemble in natural circulation boiler.\r\n4. It can easily start.\r\n5. It has high steam generation capacity of about 50 ton\/ hour.\r\n6. This boiler has higher heat transfer rate.","headline":"Constructions And Working Of Lamont Boiler | Application","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2017-04-17","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2017\/04\/lamontboiler-300x246.jpg","height":246,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/rice-transplanter-mechanism-for/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2017/04/RicetransplanterMechanismForAgriculturalPurposeProject-300x184.png')"></div><span class="sr-only">link to Rice transplanter Mechanism For Agricultural Purpose Project</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/rice-transplanter-mechanism-for/">Rice transplanter Mechanism For Agricultural Purpose Project</a></p></header><div class="excerpt"><p>Rice transplanter Mechanism For Agricultural Purpose Project  A rice transplanter is a specialized transplanter fitted to transplant rice seedlings onto paddy field.

Mainly two types of rice transplanter i.e., riding type and walking type. Riding type is power driven and can usually transplant six lines in one pass. On the other hand, walking type is manually driven and can usually transplant four lines in one pass. But both of them little cost so many of them transplant by manually.\r\nIf we rice transplanter manually, it takes lot of time to plant large plants. So we use mechanical transplanting machine. Mechanical transplanting of rice is the process of transplanting young rice seedlings, which have been grown in a mat nursery, using a self-propelled rice transplanter.\r\n\u00a0 The proposed model consists of circular wheel, lever which is linked with the planting link. By using kinematics, Kinematics is the branch of classical mechanics which describes the motion of points (alternatively \"particles\"), bodies (objects), and systems of bodies without consideration of the masses of those objects nor the forces that may have caused the motion. Kinematics as a field of study is often referred to as the \"geometry of motion\" and as such may be seen as a branch of mathematics. It is continuously drawn the rice plants into the field.\r\n\r\nWorking principle:\r\nIt works on the basics of movements produced by manually pulling. When we manually pulling the machine it automatically rotates the wheel and correspondingly it touches the lever kinematic linked to planter stick. It continuously plants until we stop our pulling.

When the tool is built, the boring bar is first clamped with both pivots at lead centre. \u00a0So, the tool describes a zero radius when the crank is turned.\r\n\r\nAt this time, one set up pin hole is drilled in each of the rotating plates, as indicated so that the pin touches the boring bar. \u00a0Then to set the tool, for a desired radius, it is merely necessary to place a piece of flat stock the same thickness as the desired radius between the bar and the set up pins while securing the bar in position. \u00a0At this point, data the flat stock and set up pin can be removed.\r\n\r\nINTRODUCTION\r\n\r\nThe concave attachment is fixed to the carriage of the lathe. \u00a0The compound rest that is locked solid with its base is removed and the attachment is fixed on the cross lied of the carriage with its axis parallel to the lathe bed.\r\n\r\n\u00a0The work is secured rigidly in a chuck. \u00a0By the concave-convex movement of the boring bar, the material is being removed. \u00a0This attachment is used to produce contour profiles and round balls.\r\n\r\nNEED FOR ATTACHMENT\r\n\r\nIn recent years, new fabrication techniques have been developed to satisfy the technological demands. \u00a0Moreover, emphasis is stressed on attachments.\r\n\r\nAttachments are used in various fields and machines depending upon the needs to be fulfilled and mode of operation. \u00a0An attachment eliminates the purchasing of a new unit which serves the same purpose. \u00a0For example, a lathe occupies a place opposite to that of a milling machine, the ten machines mainly used to produce cylindrical and plain surfaces respectively. \u00a0By implementing an attachment to a unit, the capacity of the unit can be increased which is very economical.\r\n\r\nWORKING PRINCIPLE\r\n\r\nThe worm wheel is rotated with the help of a worm shaft. \u00a0Rotating plates with T-slots that hold the boring are screwed to the worm wheel. \u00a0The worm wheel in turn is screwed to its base with a simple gear train. \u00a0The rotary motion is imported to the blank through two spur gears and an intermediate gear namely \u201cIdler Gear\u201d.\r\n\r\nThe idler gear serves to keep the rotation of rotating plates in the same direction. \u00a0The worm shaft is rotated in clockwise direction, the boring bar machines a contour profile in the clockwise direction and vice versa. \u00a0Thus a concave-convex profile is machined by boring bar by simultaneous engagement of the two plates.\r\n\r\n\r\n\r\n\r\n\r\nContour Attachment for Lathe machine\u00a0\r\n\r\nADVANTAGES\r\n\r\n\r\n \tThe unit is compact in size.\r\n \t\u00a0Less maintenance is essential\r\n \t\u00a0The unit gives long life with proper alignment of gears.\r\n \t\u00a0Jobs can be easily handled in this unit.\r\n\r\n\r\nAPPLICATIONS\r\n\r\n\r\n \t\u00a0Concave and convex profiles of desired radius can be easily turned.\r\n \t\u00a0Round balls can be produced","headline":"Contour Attachment For Lathe Machine -Mechanical Project","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2017-04-13","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2017\/04\/ContourAttachmentForLatheMachine-300x173.png","height":173,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/gate-2018-exam-pattern-syllabus-for/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2017/04/GATE-2018-300x185.png')"></div><span class="sr-only">link to GATE 2018 Exam Pattern | Syllabus for Mechanical engineering ME</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/gate-2018-exam-pattern-syllabus-for/">GATE 2018 Exam Pattern | Syllabus for Mechanical engineering ME</a></p></header><div class="excerpt"><p>GATE 2018: Registration, Application Form, Exam Dates, Notification

What will be the position of Piston Ring?\r\n\r\n\r\n\r\nIn 180 degree angle the Top ring, Second ring and Oil ring are fixed. Position the ring approximately 1 inch gap below the neck.\r\n\r\n2. What is D4D Technology used in Toyota Vigo?\r\n\u00a0\r\nD-4D is widely recognized as one of the most advanced diesel technologies on the market today. Diesel engines relied on relatively simple technology with a low-pressure mechanical injector delivering fuel to a pre-combustion chamber in the cylinder head where a single ignition \u2013 fired by the intense heat of high compression \u2013 takes place.\r\n\r\n3. What is DTSi Technology?\r\n&nbsp;\r\n\r\n \tDTSI stands for Digital Twin Spark Plug Ignition. The vehicles with DTSI Technology use 2 spark plugs which are controlled by digital circuit. It results in efficient combustion of air fuel mixture.\r\n \t\u00a0Digital - Since the spark generation will be initiated by a microchip.\r\n \tTwin - Since two spark plugs will be used.\r\n \t\r\n\r\nRead more : Seminar On DTSI Engine Free Download Pdf, PPT\u00a0\r\n\r\n&nbsp;\r\n4.What VVTi written on new cars of Toyota stands for?\r\n\r\n\r\n\r\nVVTi : Variable Valve Timing with Intelligence. It is the advanced version of the VVT engine. It changes the cam shaft position by using oil\u00a0pressure. It is similar to CVVT in Hyundai.\r\n\r\n\r\nToyota-Corolla-Altis-\r\n\r\n\r\n5. What is PGM FI technology used in Honda\u00a0Stunner Bike?\r\n\r\n\r\n\r\nThe development of an ECU-integrated throttle body module for an electronic fuel injection\r\nsystem for small motorcycles.\r\n\r\nHonda has a goal to reduce the total emissions of HC (hydro-carbon) from new vehicles to approximately 1\/3 and to further improve the average fuel economy by approximately 30 (both from 1995) by the year 2005. To realize the goal we at Asaka R AND D Center considered that the small motorcycles used in many countries in the world should be improved further for clean exhaust gas and low fuel consumption. Accordingly we have started development of the PGM-FI system for small motorcycles with engines of 125cc or smaller including air-cooled engines.\r\nTo ensure clean exhaust gas and high fuel economy the control of combustion through an accurate fuel supply is a must. As the conventional FI system (electronic fuel injection system) applied to motorcycles is bulky and costly its application has been mostly in large motorcycles using multi-cylinder engines.\r\n\r\n\u00a0In the newly developed PGM-FI in order to apply to small displacement models the obstacles have been eliminated by fully using Honda\u2019s techniques to down-size components as well as making maximum use of the FI techniques attained from the large motorcycles. The compact PGM-FI offers new benefits such as the reduction of released environmentally detrimental substances and the improvement of drivability economy etc.\r\n\r\n\r\n\r\n\r\n\r\n\r\n6. What is ATFT Technology used in Honda Hunk?\r\n&nbsp;\r\nATFT means Advance Tumble Flow Induction Technology,\r\nTumble flow means swirling. In this technology fuel air mixture from the carburator into the engine cylinder with a swirl action. The advantage being one gets a more efficient burning of fuel hence more power and better fuel economy with lesser emissions.\r\n\r\n\r\natft\r\n\r\n\r\n\u00a0\r\n7. The Compression ratio of Petrol engine is always less than Compression Ratio of Diesel engine why?\r\n\u00a0\r\nPetrol is not self igniting , it needs spark to flame up in chamber. Where as diesel is self igniting in diesel engine , to attain that state it requires high temp and pressure. This temperature and pressure is more than what\u2019s required in Petrol Engines by property of that fluid .\r\n\r\n8. What are the causes of main engine black smoke?\r\nThere is many cause of black smoke.\r\n1.is improper mixture of fuel supply by carburetor like very rich mixture so the fuel improper burn.\r\n2. it is when piston or piston ring is fail so back side cooling oil release in combustion chamber\u00a0it cause black smoke.\r\n3.improper ignition system like not sufficient time of pressure rise delay period .\r\n4.Detonation\r\n\r\n9. Explain the basic difference between BS2 and BS3 engine.\r\n\r\nThe basic difference of BS2 and BS3 engines is the presence of catalytic convertor. Catalytic convertor is present in BS3 engine which helps in reducing the formation of HC and CO. While in BS2 engine, no catalytic convertor is present which forms HC and CO. Thus in BS3 engine there is no emission of harmful CO and HC. The full form of BS is bharat stage, which is a standard of emission in India.\r\n\r\n10. What is clutch drag?\r\n\r\nWhen the clutch is not disengaging fully and provides some difficulty in changing the gears then this defect is called clutch drag.\r\n\r\n11.What are BS3 and BS4 Engines?\r\n\r\nAs per ARAI, the exhaust emissions for BS-III two-wheelers direct that the petrol-powered engine should have carbon monoxide (CO) restricted to 1.00 g\/km and Hydrocarbon + Nitrous oxide (HC + NOx) emission level should also not be more than 1.00 g\/km. For a vehicle to be BS-IV compliant its must have an emission not more than 0.75 g\/km of CO and HC+Nox respectively. This means the engines have to be new in order to emitless pollutants out helping in reduction of overall pollution from the exhaust.\r\n\r\n12.What is octane number and cetane number?\r\n\r\nOctane number can be defined as the percentage, by volume, of iso-octane in the mixture of iso-octane and h-heptane. It is the measure of rating of SI engine.\r\nWhile cetane number can be defined as the percentage,by volume, of n-cetane in the mixture of n-cetane and alpha methyl naphthalene. It is the measure of rating of CI engine.","headline":"Automobile Engineering interview questions and answers","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2017-04-13","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2017\/04\/Toyota-Corolla-Altis-2010-25-300x201.jpg","height":201,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/basic-interview-questions-2017-for/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2017/04/bearingnomenclature-300x299.jpg')"></div><span class="sr-only">link to Basic Interview Questions 2017 For Mechanical Engineering</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/basic-interview-questions-2017-for/">Basic Interview Questions 2017 For Mechanical Engineering</a></p></header><div class="excerpt"><p>Basic Interview Questions 2017 For Mechanical Engineering  1.

WHAT IS THE OTHER NAME OF MICROMETER AND VERNIER CALIPER\r\nAns: Micrometer\u2019s other name is Screw Gauze and Vernier caliper\u2019s other name is slide caliper.\r\n\r\n\r\n2. How Cavitation can be eliminated in a Pump?\r\n\r\n\r\n \tCavitation means bubbles are forming in the liquid.\r\n \tTo avoid Cavitation, we have to increase the Pump size to One or Two Inch;\r\n \tTo increase the pressure of the Suction Head,or Decrease the Pump Speed.\r\n\r\n3. Which pump is more efficient Centrifugal pump or Reciprocating pump?\r\nCentrifugal pump.\r\nBecause flow rate is higher compared to reciprocating pump. Flow is smooth and it requires less space to install. Lower initial cost and lower maintenance cost.\r\n\r\n\r\n\r\n4: State Laws of conservation of energy?\r\nAccording to the laws of conservation of\u00a0energy, \u201cenergy can neither be created nor be\u00a0destroyed. It can only be transformed from one\u00a0form to another.\u201d\r\n\r\n\r\n5. Explain the nomenclature of a 6203-ZZ bearing.\r\n6 is the type code, which shows it is a single-row ball bearing, 2 is the series, means light, 03 is the bore, which is 17 mm and ZZ is the suffix meaning double shielded bearing.\r\n\r\n\r\nBearing Nomenclature\r\n\r\n\r\n\r\n6. What are differences between Welding and Brazing?\r\nIn Welding concentrated heat (high temperature) is applied at the joint of metal and fuse together. In Brazing involves significantly lower temperatures and does not entail the melting of base metals. Instead, a filler metal is melted and forced to flow into the joint through capillary action.\r\n\r\n7. What is the difference between Blower and Fan?\r\nFan is an air pushing device. Either Axial or Centrifugal type systems are used to move the air in low pressure. It is rotated by a motor separately.\r\nWhen the fan is a housing of blades and motor, then it called as Blower. It directs the air in a single path with high pressure.\r\n\r\n8. What is the difference between Pipe and Tube?\r\n\r\n\r\n\r\n\r\n \tEx. Iron Pipe, Carbon Tube, Steel Tube etc.\r\n \tTube is defined by Outer diameter and Wall thickness (OD and WT). While Pipe is defined by Inner diameter (ID).\r\n \tTube is easily shaped by bending, where Pipe needs some mechanical work to shape it.\r\n \tTube is tight then Pipe.\r\n \tTube is applicable to non cylindrical sections like Square and Rectangular.\r\n\r\n\r\nExample:\r\n2 inch pipe have 2.375 inch outer diameter, where 2 inch tube have same 2 inch outer diameter.\r\n\r\n9. What are the differences between Weight and Mass?\r\n\r\n\u00a0\r\nMass is a measure of how much matter an object has. Mass is specified in Gram or Kilograms. Weight is a measure of how strongly gravity pulls on that matter. Force is measured in Newton\u2019s.\r\n\u00a0\r\nF=m.g\r\n\u00a0\r\nThus if you were to travel to the moon your weight would change because the pull of gravity is weaker there than on Earth but, your mass would stay the same because you are still made up of the same amount of matter.\r\n\r\n\u00a0\r\n10. What is the difference between Yield and Ultimate tensile strength?\r\n\r\nThe yield strength is reached when the material becomes Non \u2013 linear (that is non elastic) and takes a permanent set when load is released. Material stretches but does not break. Ultimate strength is when it breaks and is higher than yield strength.\r\n\r\n11. What is the difference between Bolt and Screw?\r\n\r\nThe main difference was based on the load acting on it, and the size. For smaller loads, screws are enough but in case of greater-loads, bolts are to be used. In bolt we give centrifugal force or tangential force and screw we give axial force for driving.\r\n\r\n12. Difference between TIG and MIG welding\r\n\r\nTungsten inert gas welding-non consumable electrode. MIG-Metal inert gas welding-uses consumable electrode.\r\n\r\n13. What does CC Stand for?\r\nCC is the abbreviated form of cubic centimeter. It is the unit by which the capacity of an engine is designated. It is the volume between TDC and BDC. It represents the quantity of fuel-air mix or exhaust gas that is pumped out in a single piston stroke. Alternatively it can represent the volume of the cylinder itself.\r\n\r\n\r\nMeaning Of Cubic Capacity ( CC )\r\n\r\n\r\n\r\n\r\n\r\n14. The Compression ratio of Petrol engine is always less than Compression Ratio of Diesel engine why?\r\n\r\n\r\nPetrol is not self igniting , it needs spark to flame up in chamber. Where as diesel is self igniting in diesel engine , to attain that state it requires high temp and pressure. This temperature and pressure is more than what\u2019s required in Petrol Engines by property of that fluid .\r\n\r\n\r\n15. what is BHP?\r\nBrake horsepower is the amount of work generated by a motor under ideal\u00a0conditions. This work is calculated without the consideration of effects of any auxiliary\u00a0component, that may slow down the actual speed of the motor. Brake horsepower is measured within the engines output shaft and was originally designed to calculate and compare the output of steam engines.\r\n\r\nAs per the conventions, 1 BHP equals to:\r\n\u00b7 745.5 watts\r\n\u00b7 1.01389 ps\r\n\u00b7 33,000 ft lbf\/min","headline":"Basic Interview Questions 2017 For Mechanical Engineering","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2017-04-12","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2017\/04\/bearingnomenclature-300x299.jpg","height":299,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <nav class="pagination-wrapper" aria-label="article pagination"> <a class="prev page-numbers" href="?page_num=244">&laquo; PREV</a> <a class="page-numbers" href="?page_num=1"><span class="screen-reader-text">Page </span>1</a> <span class="page-numbers dots">&hellip;</span> <a class="page-numbers" href="?page_num=243"><span class="screen-reader-text">Page </span>243</a> <a class="page-numbers" href="?page_num=244"><span class="screen-reader-text">Page </span>244</a> <span aria-current="page" class="page-numbers current"><span class="screen-reader-text">Page </span>245</span> <a class="page-numbers" href="?page_num=246"><span class="screen-reader-text">Page </span>246</a> <a class="page-numbers" href="?page_num=247"><span class="screen-reader-text">Page </span>247</a> <span class="page-numbers dots">&hellip;</span> <a class="page-numbers" href="?page_num=338"><span class="screen-reader-text">Page </span>338</a> <a class="next page-numbers" href="?page_num=246">NEXT &raquo;</a></nav></section></main><aside id="secondary" class="widget-area"><div class="about-wrapper"><h2 class="widget-title" style="background: #d693c6; color: #ff392e">About Us</h2><div class="about-image" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2020/03/Sachin-Thorat-300x300-min.png')"></div><p class="about-copy">LearnMech.Com is a Mechanical Project-oriented platform run by Sachin Thorat who is a B-Tech Graduate in Mechanical Engineering.
