Water is the working fluid in a rankine cycle. steam enters the turbine at 1400 lbf/in.2 and 1000°f. the condenser pressure is 2 lbf/in.2 both the turbine and pump have isentropic efficiencies of 85%. the working fluid has negligible pressure drop in passing through the steam generator. the net power output of the cycle is 1 × 109 btu/h. cooling water experiences a temperature increase from 60°f to 76°f, with negligible pressure drop, as it passes through the condenser. determine for the cycle (a) the mass flow rate of steam, in lb/h. (b) the rate of heat transfer, in btu/h, to the working fluid passing through the steam generator. (c) the thermal efficiency. (d) the mass flow rate of cooling water, in lb/h.
