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