Required information A Diesel cycle has a compression ratio of 22 and begins its compression at 89kPa and 15C. The maximum cycle temperature is 1200C. Utilize air-standard assumptions. The properties of air at room temperature are R=0.287kPam3/kgK,cp=1.005kJ/kgK,cV= 0.718kJ/kgK, and k=1.4 Determine the thermal efficiency of this cycle using constant specific heats at room temperature. The thermal efficiency of this cycle (in decimal fraction) is
