The compression ratio of an ideal air-powered Diesel cycle is 20. At the beginning of the compression process, the pressure of the air is 100 kPa, the temperature is 20 ° C, and the highest temperature of the cycle is required not to exceed 2250 K. Show the cycle in the P-v diagram. Accept specific temperatures constant at room temperature.
k=1.4 CP=1.005 kJ/kgK CV=0.718 kJ/kgK R=0.287 kJ/kgK
a) Calculate the temperatures entering and leaving the cycle, the thermal efficiency of the cycle,
b) Calculate the average effective pressure of the cycle.
