Extracted text: Heat-Transfer Area and Use of Log Mean Temperature Difference. A reaction mixture having a cpm 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 overall U, is 653 W/m2 K. (a) For counterflow, calculate the outlet water temperature and the area A, of the exchanger. (b) Repeat for cocurrent flow. 2.85 KJ/kg· K is flowing at a rate of 7260 kg/h and is to Ans. (a) T, = 325.2 K, A, = 5.43 m², (b) A, = 6.46 m2
