A fluid flows at 10oC flows over a 3-cm-OD and 2-m long tube, whose surface is maintained at 100oC. If the heat transfer coefficient between the tube and the fluid is 150 W/(m2 K), determine the rate of convective heat transfer from the tube to the fluid. If the outer surface of the tube has an emissivity of 0.9, and if it sees the surroundings at a temperature of 10oC, what is the net radiative heat transfer?
