A concentric tube heat exchanger uses water, which is available at 15?C, to cool ethylene glycol from 100 to 60C. The water and glycol flow rates are each 0.5 kg/s. What are the maximum possible heat transfer rate and effectiveness of the exchanger? Which is preferred, a parallel-flow or counterflow arrangement of the operation? (Discuss whether both arrangements are possible, then calculate A CF/APF if U is the same for both arrangements) Properties of water are evaluated at Tc = 30oC.
