A heat pump shown is driven by 3.0 MW motor and receives heat from a source at 60 C and deliver energy to a boiler that operates at constant pressure and saturation temperature of 140 C. The water enters the boiler as saturated liquid and leaves as saturated vapor at the same temperature. The heat pump operates with a COP (coefficient of performance) that is 60% of a Carnot heat pump COP. Find : 1- the maximum mass flow rate of water the system can deliver 2- the heat received from the source Q, boiler mter VHP W T 60°C

Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
