Question: Repeat Problem 11.47 assuming the turbine has an isentropic efficiency of 85%. Problem 11.47 A steam power plant has high and low pressures of 20
Problem 11.47
A steam power plant has high and low pressures of 20 MPa and 10 kPa, and one open feedwater heater operating at 1 MPa with the exit as saturated liquid. The maximum temperature is 800°C and the turbine has a total power output of 5 MW. Find the fraction of the flow for extraction to the feedwater and the total condenser heat transfer rate.
