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.
