In Problem 5.13.1, what throughputs can be achieved when pumping gasoline alone? Use a specific gravity of 0.74 and viscosity of 0.65 for gasoline at the flowing temperature. Compare the….
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?
