A heat exchanger is to heat water (cp = 4.18 kJ/kgoC) from 25 to 60oC at a rate of 0.2 kg/s. The heating is to be accomplished by geothermal water (cp = 2.09 kJ/kgoC) available at 140oC at a mass flow rate of 0.3 kg/s. Determine the rate of heat transfer (kW) in the heat exchanger and the exit temperature (oC) of geothermal water
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 heat exchanger is to heat water (cp = 4.18 kJ/kgoC) from 25 to 60oC at a rate
of 0.2 kg/s. The heating is to be accomplished by geothermal water (cp = 2.09 kJ/kgoC) available at 140oC at a mass flow rate of 0.3 kg/s. Determine the rate of heat
transfer (kW) in the heat exchanger and the exit temperature (oC) of geothermal
water and the exit temperature of the well steam in the heat exchanger.
