A Carnot heat pump cycle is executed in a steady-flow system with R-134a flowing at a rate of 0.216 kg/s. The net power input to the cycle is 5 kW and the ratio of the maximum-to-minimum temperatures is 1.2. If the refrigerant changes from saturated vapor to saturated liquid during the heat rejection process, plot the T-V diagram of the cycle process with saturation lines and also determine the ratio of the maximum to minimum pressures.
