8-136 A well-insulated heat exchanger is to heat water (cp = 4.18 kJ/kg · °C) from 25°C to 60°C at a rate of 0.4 kg/s. The heating is to be accomplished by geothermal water (cp = 4.31 kJ/kg · °C) available at 140°C at a mass flow rate of 0.3 kg/s. The inner tube is thin-walled and has a diameter of 0.6 cm. Determine a) the rate of heat transfer and b) the rate of exergy destruction in the heat exchanger. | |
