2. (6 pts) An experimental test setup requires coolant supplied at a precisely controlled temperature. The fluid is brought to temperature by circulating it through a very long coiled tube submerged in a temperature-controlled bath. At baseline conditions, the coolant flow in the tube has Rep = 100. a. One of your colleagues (who received an ME degree from OSU) suggests that the coolant flow rate could be doubled to increase the heat transfer coefficient in the coiled tube. They argue that this could reduce the required length of the coil. Would this approach be successful? Justify your answer. b. A second colleague (who received an ME degree from Pitt) suggests that the standard tubing should be replaced with highly polished tubing of equal length and dimensions. They argue that using the smoother walled tubing could reduce the pump work required to circulate the flow. Would this approach be successful? Justify your answer.
