1. A low-temperature power plant operates with R-410a maintaining -20?C 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 60?C, 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 -10?C in the condenser, a high pressure of 6 MPa, and it superheats to 100?C. Find the turbine exit temperature, the mass flow rate required, and the overall cycle efficiency.
