Consider the flow of oil at 20oC in a 40-cm-diameter pipeline at an average velocity of 0.5 m/s. A 300-m-long section of the pipeline passes through icy waters of a lake at 0°C. Measurements indicate that the surface temperature of the pipe is very nearly 0°C. Disregarding the thermal resistance of the pipe material, determine the temperature of the oil when the pipe leaves the lake, and the rate of heat transfer from the oil ρ=893.5 kg/m3 Cp=1838 J/kgoC, k=0.146W/m ̊C, Pr=28750, V = 259,1x10-5 m2/s
