Engine oil is the lifeblood of your vehicle‚ it ensures minimum wear on engine components and maximum engine performance. Understanding how to change your engine oil is an essential skill of DIY car maintenance. Your vehicle’s owner manual will help you determine when to change your vehicle’s engine oil. If you drive short distances regularly‚ tow heavy loads‚ or competing track days you’ll need to change your engine more frequently. To change your vehicle’s engine oil‚ you’ll need a jack and axle

The new Wolfram/Alpha Search engine‚ however‚ tries to compete with Google and other similar search engines by “researching” rather than just “searching” data. Stephen Wolfram‚ the new search engine creator gives an example; for a question like "How many Nobel Prize winners were born under a full moon?" Google would find the answer only if someone had previously

How did the Speed of the Steam Engine Change America Introduction The steam engine was the most important discovery for the development of America from a farming country to a country which could produce goods in factories. The Industrial Revolution which started in Europe happened in America in the middle of the nineteenth century. The use of steam engine powered boats‚ ships‚ railways and factories is how the industrial revolution is how America was able become more productive and powerful country

1. A reciprocating engine automatic mixture control responds to changes in air density caused by changes in Altitude or temperature 2. On a float-type carburetor‚ the purpose of the economizer valve is to Provide a richer mixture and cooling at maximum power output 3. The fuel metering force of a conventional float-type carburetor in its normal operating range is the difference between the pressure acting on the discharge nozzle located within the venture and the pressure Acting on

Thermodynamics within a Heat Engine Physical chemistry can be considered anything that undergoes a physical or chemical change using the underlying concepts of mathematics and physics. According to chemist Gilbert Newton Lewis‚ “Physical chemistry is everything that is interesting” (ACS). When you think about it‚ physical chemistry is all around us in the world we live in today. Some aspects of physical chemistry can even range anywhere from tropical storms to turbines‚ or steam engines and just about everything

that a heat pump receives heat Q2 from low temperature reservoir at T2 and supplies it to high temperature sink at T1 without any external work‚ thus violating the Clausius statement. A larger quantity of heat (Q1 + Q2) is supplied to heat engine (by high temperature source at T1) Which produces net work output Wnet equal to Q1 and rejects an amount of heat Q2 to low temperature reservoir. The composite of two devices is shown in Fig. (b). It shows that the heat pump helps the heat Q2 to
