A well-insulated, thin-walled, counterflow heat exchanger is to be used to cool oil (cp = 2.20 kJ/kg·°C) from 150 to 40°C at a rate of 2 kg/s with water (cp = 4.18 kJ/kg·°C) that enters at 22°C at a rate of 1.5 kg/s. The diameter of the tube is 2.5 cm, and its length is 6 m. Determine the rate of exergy destruction in the heat exchanger.
