During the isothermal expansion, the water is heated until it is saturated vapor from an initial state where the pressure is 15 bar and the quality is 25%. The vapor then expands adiabatically to a pressure of 1 bar while doing 403.8 kJ/kg of work. a.) Sketch the cycle on PV coordinates. b.) Evaluate the heat and work for each process, in kJ c.) Evaluate the thermal efficiency.

One and one-half pounds of water within a piston-cylinder assembly execute a Carnot power cycle. During isothermal expansion, the water is heated at 500 degree F from saturated liquid to saturated vapor. The vapor then expands adiabatically to a temperature of 100 degree F and a quality of 70.38%. Sketch the cycle on p-v coordinates. Evaluate the heat transfer and work for each process, in Btu. Evaluate the thermal efficiency.
