Qu) An air engine works on the following cycle: Air is taken in at atmospheric pressure of 110 kpa and temperatur of 16 °C, and is Gompressed adiabatically, the pressure at the end of the stroke being 3500 kpa. Heat is taken in at Gnstant Pressure, the expansion afterwards takes place adiabatically, the ratio of expansion being S, The air is exhausted at the end of the strok, the heat is assumed to be rejected at constant volume. Find the ideal thermal efficiency. Take the Specific heats of air as CP=1.0035 kJ/kg. k and Cv=0.7165 kJ/kg.k.
