The figure below shows a vapor power cycle that provides process heat and produces power. The steam generator produces vapor at
500 lbf/in.2, 800°F, at a rate of 4.4 x 105 lb/h. Eighty-eight percent of the steam expands through the turbine to 10 lbf/in.² and the
remainder is directed to the heat exchanger. Saturated liquid exits the heat exchanger at 500 lbf/in.2 and passes through a trap before
entering the condenser at 10 lbf/in.²
Saturated liquid exits the condenser at 10 lbf/in.² and is pumped to 500 lbf/in.2 before entering the steam generator. The turbine and
pump have isentropic efficiencies of 85% and 89%, respectively. For the process heat exchanger, assume the temperature at which
heat transfer occurs is 465°F. Let To = 60°F. Po = 14.7 lbf/in.²
