At steady state, a refrigeration cycle operating between hot and cold reservoirs at 300 Kand 235 K, respectively, removes energy by heat transfer from the cold reservoir at a rate of 100 kW. (a) If the cycle's coefficient of performance is 4, determine the power input required, in kW. (b) Determine the minimum theoretical power required, in kW, for any such cycle.
