Oil flowing at a rate of 180 kg/min enters a parallel double pipe heat exchanger at 25°C and is heated by a water stream flowing at rate of 300 kg/min and entering to the heat exchanger at 80°C. Calculate oil exit temperature. Take Cpoil = 2 kJ/kgK, Cp,water = 4.2 kJ/kgK, U = 400 W/m²K and A = 10m².
