The hot combustion gases of a furnace are separated from the ambient air and its surroundings, which are at 25 oC, by a brick wall 0.15 m thick. The brick has a thermalconductivity of 1.2 W/m. K and a surface emissivity of 0.8. Under steady state conditions an outer surface temperature of 100 oC is measured. Free convection heat transfer to the air adjoining this surface is characterized by a convection coefficient h = 20 W/m2.K. What is the inner surface temperature of the brick?
