1. In 1939, the Port Washington, Wisconsin, power plant of the Milwaukee Electric Railway and Light Company14 had an unusually high heat rate of 10,800 Btu/(kW · h). Determine its thermal efficiency.
2. Refrigerant-22 is used as the working fluid in a 1.00 MW Rankine bottoming cycle for a steam power plant. The bottoming cycle turbine inlet state is saturated vapor at 210.°F, and the condenser outlet is saturated liquid at 70.0°F. The turbine and pump isentropic efficiencies are 85.0% and 70.0%, respectively. Determine
a. The thermal efficiency of the bottoming cycle.
b. The ratio of the pump to turbine power.
c. The required mass flow rate of refrigerant.
