10 kg of air occupying a cylinder volume of 0.28 m3 is allowed to expand isentropically behind a piston to a pressure of 30 bar. The air is then heated at a constant volume. Finally, the air is cooled at a constant pressure back to its initial conditions. The initial pressure is 60 bar. Calculate the change in entropy, the net work done and the net heat flow. Sketch the cycle on the p‐v and T‐s diagrams.
