15,000 kg/h of a fluid at 15°C, whose specific heat is 3.817 kJ/(kg °C), is being processed in a food industry. In order to improve energy performance, it is desired to install a heat exchanger to increase the temperature of the fluid up to 72°C, using a water stream of 20,000 kg/h that comes from the condensation of steam at 100oC. Calculate the surface of a heat exchanger for circulation in countercurrent, if the overall heat-transfer coefficient is 1750 W/(m2 °C). Specific heat of water is 4.185kJ/kg°C. Is concurrent flow possible? Explain your answer.
