Figure shows a simple vapor power cycle operating at steady state with water as the working fluid. Data at key locations are given on the figure. The isentropic efficiency of the turbine is 88%. The pump is isentropic. Flow through the steam generator and condenser occurs at constant pressure. Stray heat transfer and kinetic and potential energy effects are negligible. a) Determine the power produced by the turbine, in kW. b) Determine the mass flow rate of the cooling water flowing through the condenser, in kg/s. c) Determine the entropy production in the turbine, in kW/K. d) Determine the entropy production in the condenser, in kW/K. ėn m,=20 kg/s P1 = 20 MPa T = 700°C %3D Power out Turbine 1 n=0.88 P2 = 0.20 bar Steam 2 generator Cooling water in Tin=25°C Condenser Tout=38°C 4+ P4 = 20 MPa Cooling water out Pump 3 P3=0.20 bar T3 = 40°C Power in Figure shows a simple vapor power cycle operating at steady state with water as the working fluid.
