Question:
A concentric tube heat exchanger uses water, which is available at \(25^{\circ} \mathrm{C}\), to cool ethylene glycol from 110 to \(70^{\circ} \mathrm{C}\). The water and glycol flow rates are each \(0.25 \mathrm{~kg} / \mathrm{s}\). What are the maximum possible heat transfer rate and effectiveness of the exchanger? Which is preferred, a parallel-flow or counterflow mode of operation?
