Water flowing at a rate of 0.667 kg/s (Cp = 4.192 kJ/kg. K) enters a counter current heat exchanger at 318 K and is heated by an oil stream entering at 393 K at a rate of 2.85 kg/s (Cp=1.89 kJ/kg. K). The overall U=290 W/m2. K and the area A=20 m2. Calculate the heat transfer rate and the exit water temperature.
