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
