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 5008F from saturated liquid to saturated vapor. The vapor then expands adiabatically to a temperature of 1008F and a quality of 70.38%.
(a) Sketch the cycle on p-y coordinates.
(b) Evaluate the heat transfer and work for each process, in Btu.
(c) Evaluate the thermal efficiency.
