Extracted text: Cooling Oil and Overall U. Oil flowing at the rate of 7258 kg/h with a cpm = 2.01 kJ/kg K is cooled from 394.3 K to 338.9 K in a counterflow heat ex- changer by water entering at 294.3 K and leaving at 305.4 K. Calculate the flow rate of the water and the overall U; if the A; is 5.11 m². Ans. 17420 kg/h, U; = 686 W/m² · K
