The hot combustion gases of a furnace are separated from the ambient air and its surrounding which are at 25°C, by a brick wall 0.15 m thick. The brick has a thermal conductivity of 1.2 W/m-K and a surface emissivity of 0.80. Under steady state conditions and outer surface temperature of 100°C is measured. Free convection heat surface to the air adjoining this surface is characterized by a convection coefficient of 20 w/m2-K. What is the inner surface temperature in °C? Use the editor to format your answer
