Acooling coil, consisting of a single length of tubing through which water is circulated, is provided in a liquid tank. the contents of the liquid tank are kept uniformly at 360 k by means of a stirrer. the inlet and outlet temperatures of the cooling water are 275 k and 315 k respectively. what would the outlet water temperature become if the length of the cooling coil were increased 4 times? assume the overall heat transfer coefficient to be constant over the length of the tube and independent of water temperature.
