A Rankine cycle power plant is to be used as a stationary power source for a polar research station. The working fluid is Refrigerant-22 at a flow rate of 9.00 lbm/s, and the turbine inlet state is saturated vapor at 200.°F. The condenser is air cooled and has an internal temperature of 0.00°F.
Assuming a turbine and pump isentropic efficiency of 85.0% and that the refrigerant leaves the condenser as a saturated liquid, determine the overall thermodynamic efficiency and the net power output of the system.
