A mass of air is initially at 206°C at pressure of 7bar and having volume of 0.03m3.The air is expanded at constant pressure to 0.09m3,a polytropic process with index (1.5) is then carried out followed by a constant temperature process which completes the cycle. Determine : 1. The total work done on or by the system 2. The ratio of the rejected to added heat
