Question: Example A two - layer wall has a total exposed surface area of 1 2 5 0 m 2 . The temperature of the hotter

Example
A two-layer wall has a total exposed surface area of 1250 m 2. The temperature of the hotter side is 850C; the temperature of the cooler side is 85C. The layer closer to the hotter side is 0.75 m thick and has a thermal conductivity of 145Wm*K. The layer closer to the cooler side is 1.55 m thick and has a thermal conductivity of 25Wm*K. What is the thermal resistance of the wall?
