A reversible refrigeration cycle operates between cold and hot reservoirs at temperatures TC and TH, respectively. (a) If the coefficient of performance is 10 and TC = -40°F, determine TH, in °F. (b) If TC = 0°C and TH = 30°C, determine the coefficient of performance. (c) If QC = 500 Btu, QH = 600 Btu, and TC = 20°F, determine TH, in °F. (d) If TC = 30°F and TH = 100°F, determine the coefficient of performance. (e) If the coefficient of performance is 8.9 and TC = -5°C, find TH, in °C.
