A diesel cycle with air as the working fluid has a compression ratio of 20. The temperature and pressure in the first process is 20°C, 95kPa and the highest attainable temperature is 1927°C. The air standard assumptions are applicable, both Kinetic and Potential energy are negligible. The mass/mass flow rate is negligible. Use the standard constants for air (Cp, Cy. R, and k). Determine the amount of heat transferred and rejected, the net work and thermal efficiency, and the mean effective pressure.
