Question details

4. Figure shows a vapor power cycle that provides process heat and produces power. The steam generator produces vapor at 500 lbf/in2, 800°F, at a rate of 8*104 lb/h. Eighty-eight percent of the steam expands through the turbine to 10 lbf/in and the remainder is directed to the heat exchanger. Saturated liquid exits the heat exchanger at 500 lbf/in2 and passes through a trap before entering the condenser at 10 lbf/in2 Saturated liquid exits the condenser at 10 lbf/in and is pumped to 500 lbf/in2 before entering the steam generator. The turbine and pump have isentropic efficiencies of 85% and 89%, respectively. Determine (a) The process heat production rate, in Btu/h (b) The thermal efficiency of the cycle 1 m,#8x10 lb/h 8.5% Steam gencrator 1 (I-) TurbineW P2- 10 lbtin2 exchanger i -500 lbtin.2 saturated liquid Pump P 10 lbfin.2 saturated liquid 89%
