It is desired to cool the oil with water using a parallel directional double-pipe heat exchanger. The oil flowing at a speed of 5 kg/s is cooled from 360 K to 330 K using water entering at 280 K at a speed of 2 kg/s. What is the outlet temperature of the water for a heat exchanger operating under these conditions? Assume the Cpm values for oil and water are 2.0 kJ/kg.K and 4.187 kJ/kg.K, respectively.
