Q1) A polished metal pipe (8 cm) outside diameter and 350 K temperature at the outer surface is exposed to ambient conditions at 285 K temperature. The emissivity of the surface is 0.3 and the convection coefficient of heat transfer is 13.5 W/m2-deg. What would be the overall coefficient of heat transfer by the combined mode of convection and radiation?
