A system consisting of 1 kg of H2O undergoes a power cycle composed of the following processes:
Process 1-2: Constant-pressure heating at 1 MPa from saturated vapor
Process 2-3: Constant-volume cooling to p3 = 500 kPa, T3 = 160 degree Celsius
Process 3-4: Isothermal compression with Q34 = -815.8 kJ
Process 4-1: Constant-volume heating.
Sketch the cycle on T-v and p-v diagrams. Neglecting kinetic and potential energy effects, determine the work and heat transfer.
