Water is the working fluid in a Rankine cycle. Steam
Chapter 8, Problem 8.19(choose chapter or problem)
Water is the working fluid in a Rankine cycle. Steam enters the turbine at 1400 lbf/in.\(^{2}\) and 1000\(^{\circ}\)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 X 10\(^{9}\) Btu/h. Cooling water experiences a temperature increase from 60\(^{\circ}\)F to 76\(^{\circ}\)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.
