Pressure and temperature at the start of compression in a standard diesel cycle are 95 kPa and 300 k. At the end of the heat addition, the pressure is 7.2 MPa and the temperature is 2150 k. using a cold air analysis: ( Cp = 1.005 kJ/kg.k, Cv = 0.718 kJ/kg.k, R = 0.287 kPa.m^3/kg.k). Find the compression ratio, cutoff ratio, the thermal efficiency, the mean effective pressure, and the P -v and T-s diagrams clearly showing all corners.
