Problem
1. A utility runs a Rankine cycle with a water boiler at 3.0 MPa, and the cycle has the highest and lowest temperatures of 450oC and 60oC, respectively. Find the plant efficiency and the efficiency of a Carnot cycle with the same temperatures.
2. The power plant in the previous problem has too low a quality in the low-pressure turbine section, so the plant wants to increase the superheat. What should the superheat be so that the quality of the water in the turbine stays above 92%?
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.
