Two and a half kg of an ideal gas with R = 296.9 J/(kg)(K) and c v = 0.7442 KJ/(kg)(K) at a pressure of 827.4 kPa and a temperature of 667 ̊C reject 132.2 kJ of heat at constant pressure. The gas is then expanded according to pV 1.25 = C to a point where a constant volume process will bring the gas back to its original state. Determine P3 , QA , and the power in kW for 100 Hz.
