The initial conditions for an air-standard Otto cycle operating with a compression ratio of 8:1 are 95 kPa and 17o C. At the beginning of the compression stroke, the cylinder volume is 2.20 L ( 1 L=0.001 m3)and 3.60 kJ of heat is added during the constant volume heating process. Calculate the pressure and temperature at end of each process of the cycle, and determine the thermal efficiency and mean effective pressure of the cycle.
Q. Explain why does heated air expand? Answer:- Temperature is habitually defined as the average thermal energy of the substance at hand. Therefore the hotter a substance

If a ring were constructed as knid of a space station. How fast must a 50.0-m-radius ring rotate to simulate Earth's gravity?
Power factor improvement: The low power factor is because of the fact that most of the power loads are inductive and thus take lagging currents.
