Q7: An amount of a perfect gas has initial conditions of volume (1 m³), pressure (1 bar) and temperature (18 °C). It undergoes ideal Diesel cycle operation, the pressure after isentropic compression being (50 bar) and the volume after constant pressure expansion being (0.1 m³). Calculate the temperature at the major points of the cycle and evaluate the thermal efficiency of the cycle. Assume y=1.4 for the gas Answers T2-890 K, T3 1455 K, T4-579 K, 63.59%
