Along semi-cylindrical duct has a diameter 1.0m. its base surface can be approximated as black, and heat is supplied from the base at a rate of 1200w/m-. the side surface has an emissivity of 0.4 and is maintained at 375°c. neglecting the end effects, determine the temperature of the base surface (assume the surfaces are opaque, diffuse and gray, and the convection heat transfer is not considered.)
