Problem
A steam power plant operates with a boiler output of 20 kg/s steam at 2 MPa, 600oC. The condenser operates at 50oC, dumping energy into a river that has an average temperature of 20oC. There is one open FWH with extraction from the turbine at 600 kPa, and its exit is saturated liquid. Find the mass flow rate of the extraction flow. If the river water should not be heated more than 5oC, how much water should be pumped from the river to the heat exchanger (condenser)?
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
