4. A furnace is constructed with 225 mm of firebrick, 120 mm of insulating brick, and 225 mm of building brick. The inside temperature is 1200 K and the outside temperature is 330 K. If the thermal conductivities are 1.4,0.2 and 0.7 W/m. K, find the heat loss per unit area and the temperature at the junction of the firebrick and insulating brick
