Problem
1 A low-temperature power plant operates with R-410a maintaining 60 psia in the condenser, a high pressure of 400 psia with superheat. Find the temperature out of the boiler/super heater so that the turbine exit temperature is 20 F, and find the overall cycle efficiency.
2. A smaller power plant produces 50 lbm/s steam at 400 psia, 1100 F in the boiler. It cools the condenser with ocean water coming in at 60 F and returned at 65 F so that the condenser exit is at 110 F. Find the net power output and the required mass flow rate of the ocean water.
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.
