A new plastic-molding facility has a large amount of waste heat available at 300.°F. The local environmental temperature is 75.0°F. As an entry-level engineer, you are to investigate possible energy savings by determining
a. The thermal efficiency of a Carnot engine operating between these temperatures.
b. The coefficient of performance of a Carnot heat pump operating between these temperatures.
c. The coefficient of performance of a Carnot refrigerator operating between these temperatures.
