What are the coefficient of performance of the Carnot refrigerator and the thermal efficiency of the Carnot engine?
A Carnot refrigerator removes energy at a rate of 300 Btu/hr from a low-temperature thermal reservoir at −160 F. The high-temperature reservoir for the refrigerator is the atmosphere at 40 F. A Carnot engine operating between a reservoir at 1140 F and the atmosphere (40 F) drives this Carnot refrigerator.
A. At what rate must heat be supplied (Btu/hr) to the Carnot engine from the 1140-F reservoir?
B. What is the power input to the Carnot refrigerator (Btu/hr)?
C. What are the coefficient of performance of the Carnot refrigerator and the thermal efficiency of the Carnot engine?
