Mechanical Engineering

The compression ratio of an ideal air-powered Diesel cycle is20. At the beginning of the compression process, the pressure ofthe air is 100 kPa, the temperature is 20 ° C, and the highesttemperature of the cycle is required not to exceed 2250 K. Show thecycle in the P-v diagram. Accept specific temperatures constant atroom 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.
