2.1. Consider the flow of oil at Tol 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 (a) the temperature of the oil when the pipe leaves the lake, and (b) the rate of heat transfer from the oil v = 259,1 × 10* m²/s p=893.5 kg/m³, Cp=1838 J/kg°C, k=0.146W/m'C, Pr=28750, Toil = 20 C

2.1. Consider the flow of oil at Ton 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 (a) the temperature of the oil when the pipe leaves the lake, and (b) the rate of
heat transfer from the oil
p=893.5 kg/m³, Cp=1838 J/kg°C, k=0.146W/m°C, Pr=28750. D = 259,1× 10* m²/s
Toil = 20 C
