Water is the working fluid in an ideal Rankine cycle. Steam enters the turbine at 1400 lbf/in2 and 1000°F. The condenser pressure is 2lbf/in^2. Both turbine and pump have isentropic efficiencies of 85%. The working fluid has negligible pressure drop in passing through thee the steam generator. The net power output of the cycle is 1 x 10^9 Btu/hr. Cooling water experiences a temperature increase from 60°F to 76°F, with negligible pressure drop, as it passes through the condenser. Determine
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.
