a liquid food product is being cooled from 80C to 30C in an indirect heat exchanger using cold water as a cooling medium. Is the product mass flow rate is 1800 kg/h, determine the water flow rate required to accomplish product cooling if the water is allowed to increase from 10C to 20C in the heat exchanger. The specific heat of the product is 3.8 kJ/kg K and the value for water is 4.1 kJ/kg K.
