0.5 kg of water executes a Carnot power cycle. During the isothermal expansion (1-2), the water is heated until it is saturated vapor from an initial state where the pressure is 15 bars and the quality is 25%. The vapor then expands adiabatically to a pressure of 1 bar while doing 403.8 KJ/kg of work (2-3). Next there is isothermal compression (3-4) to a quality of 33.75%. a. Sketch the cycle on a P-v diagram. b. Find the heat and work for each process in KJ. c. Evaluate the thermal efficiency using both the ratio of net work to heat in, and using the calculated temperatures.
