In a 1 -1 counter flow shell and tube heat exchanger, a process stream (CP = 4.2 kJ/(kg.K) ) is cooled from 450 to 350 K using water ( CP = 4.2 kJ/(kg.K) ) at 300 K. The process stream flows on the shell-side at a rate of 1 kg/s and the water on the tube-side at a rate of 5 kg/s. If the heat transfer coefficients on the shell and tube sides are 1000 W/(m².K) and 1500 W/(m?.K), respectively, determine (8) the required heat transfer area. (b) by what factor will the required area change if the flow is concurrent? Neglect tube wall resistance and fouling resistances.
