A piston-cylinder assembly contains 5kg of water that undergoes a series of processes to form a thermodynamic cycle. Process 1Ã 2: Constant pressure cooling from p1=20bar and T1=360Â°C to saturated vapor Process 2Ã 3: Constant volume cooling to p3=5 bar Process 3Ã 4: Constant pressure heating Process 4Ã 1: Polytropic process following Pv =constant back to the initial state Kinetic and potential energy effects are negligible. Calculate the net work for the cycle in kJ.
