A system consisting of 1 kg of H2O undergoes a power cycle composed of the following processes: Process 1–2: Constant-volume heating from p1 5 5 bar, T1 5 1608C to p2 5 10 bar. Process 2–3: Constant-pressure cooling to saturated vapor. Process 3–4: Constant-volume cooling to T4 5 1608C. Process 4–1: Isothermal expansion with Q41 5 815.8 kJ. Sketch the cycle on T– and p– diagrams. Neglecting kinetic and potential energy effects, determine the thermal efficiency
