Refrigeration and Heat Pump Cycle Applications
As shown in Fig. P5.70, a heat pump provides energy by heat transfer to water vaporizing from saturated liquid to saturated vapor at a pressure of 2 bar and a mass flow rate of 0.05 kg/s. The heat pump receives energy by heat transfer from a pond at 16°C. These are the only significant heat transfers. Kinetic and potential energy effects can be ignored. A faded, hard-to-read data sheet indicates the power required by the pump is 35 kW. Can this value be correct? Explain.
Step 1 of 3
We are required to comment on the power required by the pump. For that, we need to calculate the power from the data given.
