Problem
A Rankine steam power plant should operate with a high pressure of 3 MPa and a low pressure of 10 kPa, and the boiler exit temperature should be 500oC. The available high-temperature source is the exhaust of 175 kg/s air at 600oC from a gas turbine. If the boiler operates as a counter flowing heat exchanger where the temperature difference at the pinch point is 20oC, find the maximum water mass flow rate possible and the air exit temperature.
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.
