An oil flowing at a rate of 2.85 kg/s (Cp = 1.89 kJ/kg K) enters a countercurrent heat exchanger at 383 K and is cooled by a stream of water entering at a rate of 0.667 kg/s and 308 K. The total U = 300 W/m2 K and the area A = 15.0 m2. Calculate the rate of heat transfer and the temperature of the leaving oil.
