A polished metal pipe 5 cm outside diameter and 370 K temperature at the outer surface is exposed to ambient conditions at 295 K temperature. The emissivity of the surface is 0.2 and the convection coefficient of heat transfer is 11.35 W/m2-K. Calculate the heat transfer by radiation and natural convection per meter length of the pipe. What would be the overall coefficient of heat transfer by combined mode of convection and radiation.
