Refrigerant-134a flows through a carnot heat pump cycle at 0. 2 kg/s. It is known that the maximum absolute temperature in the cycle is 1. 3 times the minimum absolute temperature, and the net power input to the cycle is 5 kw. If the refrigerant changes from a saturated vapor to a saturated liquid during the heat rejection process, determine the ratio of the maximum to minimum pressures in the cycle.
