Question
As shown below, 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 oC. These are the only significant heat transfers. Kinetic and potential energy effects can be ignored. You find a torn data sheet that indicates the power required by the pump is 35 kW. Can this value be correct? Explain.
