Consider the flow of engine oil at 10˚c in a 40-cm diameter pipeline at an average velocity of 0.5 m/s. a 1500-m long section of the pipeline passes through icy waters of a lake at 0˚c. disregarding the thermal resistance of the pipe material, determine (a) the temperature of the oil when the pipe leaves the lake (b) the rate of heat transfer from the oil and (c) the pressure losses in the pipe. assume the flow is hydro-dynamically fully developed.
