1.5 pounds of water within a piston-cylinder assembly execute a Carnot power cycle. During isothermal expansion, the water is heated at 500 F from saturated liquid to saturated vapor. the vapor then expands adiabatically to a temperature of 100 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
