A two-layer has a total exposed surface area of 120 m2 per side. The temperature of the hotter side is 550oC; and the temperature for the cooler side is 200oC. The layer closer to the hotter side is 0.3 m thick and has a thermal conductivity of 200 W/m. K. The layer closer to the cooler side is 0.5 m thick and has a thermal conductivity of 50 W/m. K. Most nearly, what is the thermal resistance of the wall
