Problem
1. A low-temperature power plant operates with R-410a maintaining -20oC in the condenser and a high pressure of 3 MPa with superheat. Find the temperature out of the boiler/super heater so that the turbine exit temperature is 60oC, and find the overall cycle efficiency.
2. A low-temperature power plant should produce turbine work of 2.5 MW. It operates with carbon dioxide maintaining -10oC in the condenser, a high pressure of 6 MPa, and it superheats to 100oC. Find the turbine exit temperature, the mass flow rate required, and the overall cycle efficiency
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.
