The inner and outer surfaces are at 870°C and 40°C respectively. The respective coefficient of the thermal conduciveness of the layer are 1.0, 0.12, and 0.75 W/mK and thickness are 22 cm,7.5 cm, and 11 cm. Assume close bonding of the layers at their interfaces. Find the the total thermal resistace of a furnace wall that is made up of three layers, one of fire brick, one of insulating brick and one of red brick
