1000 kg/h of milk is heated in a heat exchanger from 45^oC to 72^oC. Water is used as the heating medium. It enters the heat exchanger at 90^oC and leaves at 75^oC. Calculate the mass flow rate of the heating medium, if the heat losses to the environment are equal to 1 kW. The heat capacity of water is given equal to 4.2 kJ/kg^oC and that of milk 3.9 kJ/kg^oC.
