Problem
1. The effect of evaporator temperature on the COP of a heat pump is to be studied. Consider an ideal cycle with R-134a as the working fluid and a condenser temperature of 40oC. Plot a curve for the COP versus the evaporator temperature for temperatures from +15 to -25oC.
2. A hospital requires 2 kg/s steam at 200oC, 125 kPa for sterilization purposes, and space heating requires 15 kg/s hot water at 90oC, 100 kPa. Both of these requirements are provided by the hospital's steam power plant. Discuss some arrangement that will accomplish this.
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.
