Silicone oil is to be cooled from 100C to 65C in a concentric tube heat exchanger having a total outside area of 0.045m2. For cooling a stream of ethylene glycol amounting to 4000kg/h at a temperature of 38C is available. The exchanger consist of schedule 8021/4 in pipe in schedule 402 in pipe. The silicone oil flow rate is 4500kg/h. If the flow is counter-current, a) What is the ethylene glycol outlet temperature, logarithmic mean temperature difference and overall heat transfer coefficient. b) Represent temperature distribution (Cp silicone oil =0.55kcal/kgC,Cp ethylene glycol =0.45kcal/kgC)
