A Carnot heat pump cycle is executed in a steady-flow system with R-134a flowing at a rate of 0.21567 kg/s. The net power input to the cycle is 5 kW and the ratio of the maximum to minimum temperature is 1.2. If the refrigerant changes from saturated vapor to saturated liquid during the heat rejection process, (a) plotT-v diagramof the Carnot cycle process with saturation lines, (b) determine the temperature THduring the cycle process.

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
