A heat exchanger is to heat water (Cp= 4.18 KJ/Kg.C ) from 25 to 60 C at rate of 0.2 kg/s. the heating is to be accomplished by geothermal water ( Cp= 4.31 KJ/Kg.c ) available at 140C at a mass flow rate of 0.3Kg/s. Determine the rate of heat transfer in the heat exchanger and the exit temperature of geothermal water.
