A furnace wall consists of two layers. 9 inches of firebrick (k=0.8Btu/(hrft∘F) and 5 inches of insulating brick. (k=0.1Btu/(hrft∘F) the inside air temperature is 3000∘F and the convection coefficient inside is 12Btu/(hrft2∘F) The outside air temperature is 80∘F and the convective heat transfer coefficient is 2.0Btu/(hrft2∘F). Neglecting contact resistance between the 2 layers calculate (a) the heat loss per quare foot (b) the inner surface temperature (c) the outer surface temperature.
