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

Question

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.
