At steady state, a reversible refrigeration cycle discharges energy at the rate QH to a hot reservoir at temperature TH, while receiving energy at the rate QC from a cold reservoir at temperature TC. a. If TH = 13°C and TC = 2°C, determine the coefficient of performance. b. If QH = = 10.5 kW, 8.75 kW QC , and TC = 0°C, determine TH, in °C. c. If the coefficien
