A liquid food having aCpm= 2.85 kJ/kg⋅K is flowing at
a rate of 7260 kg/h and is to be cooled from 377.6 K to 344.3 K. Cooling water at 288.8 K is available and the flow rate is 4536 kg/h. The overallUo is 653 W/m2⋅K and mean heat capacity of water is 4.181 kJ/kg⋅K. Calculate the outlet water temperature and the areaAo of the exchanger for
(i) Counter-flow;
