Consider the flow of oil at 40C in a 30cm diameter pipeline at an average velocity of 12m/s. A 200m long section of pipeline passes through icy waters of a lake at 0C. Measurements indicate that the surface temperature of the pipe is very nearly 0C. Disregarding the thermal resistance of the pipe material, determine the rate of heat transfer from the oil and the temperature of the oil when the pipe leaves the lake.
