Question

13 Water is the working fluid in a Rankine cycle. Steam enters the turbine at 1400 lbf/in² and 1000°F. The condenser pressure is 2 lbf/in? 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 1x10° 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 o the mass flow rate of steam, in lb/h. the rate of heat transfer, in Btu/h, to the working fluid passing through the steam generator. ) the thermal efficiency. the mass flow rate of cooling water, in lb/h.
