Heat-transfer area and use of log mean temperature difference. a reaction mixture having a cpm = 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 overall uo is 653 w/m2 · k. for counterflow, calculate the outlet water temperature and the area ao of the exchanger. repeat for cocurrent flow.
