A liquid food product is being cooled from 80oC to 30oC in an indirect heat exchanger (food does not mix with heat exchanger water) using cold water as a cooling medium. The product mass flow rate is 1800kg/h Determine the cooling water flow rate required to accomplish product cooling if the water is allowed to increase from 10oC to 20oC in the heat exchanger. Display your answers on a block diagram. The specific heat of the product is 3.8 kJ/(kg K) and the value for water is 4.1 kJ/(kg K).
