In a cross flow, both fluids unmixed heat exchanger has water at 6°C flowing at rate of 1.25 kg/s. It is used to cool 1.2 kg/s of air that is initially at a temperature of 50°C. Calculate the exit temperature of air and exit temperature of water. Assume overall heat transfer coefficient is 130 W/m2K and area is 23 m2.
