Consider a Carnot heat pump cycle executed in a steady-flow system in the saturated liquid-vapor mixture region of R-134a. The R-134a is flowing at a rate of 0.264 kg/s. It is known that the maximum absolute temperature in the cycle is 1.25 times the minimum absolute temperature, and the net power input to the cycle is 7 kW. If the refrigerant changes from saturated vapor to saturated liquid during the heat rejection process, determine the ratio of the maximum and minimum pressures in the cycle. HINT: Recall that hfg = hg – hf
