(B) A furnace wall is composed of three layers, 10 cm of fire brick (k= 1.56 W/m. K), followed by 23 cm of insulating brick (k= 0.037W/m. K) and 5cm of masonry brick (k= 1 W/m. K). The temperature of the inner wall surface is 1370K and the outer surface is at 360K. Calculate the rate of heat transfer per unit area and the interface temperatures.
