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.

A centrifugal pump must be installed 6 m above the water level in a tank. the bomb will operate at a rate of 0.01 m³/s. The manufacturer suggests a pump with NPSHR at this flow rate of 2.5 m. Neglect friction losses, with the exception of a heat exchanger between the tube inlet and pump suction, which has a loss coefficient Cf = 15. The pipe diameter is 15 cm and the pressure of water vapor at 30°C is 4.246 kPa. Is this pump suitable for the given conditions?
