A layer of cork 6 inch thick is used as layer of thermal insulation in a flat wall. The temperature of the cold side is 40 oF and that of the warm side is 180 oF. The thermal conductivity of the cork at 32 oF is 0.021 Btu/ft-h-oF and that at 200 oF is 0.032. The area of the wall is 25 ft. Estimate the rate of heat transfer through the wall. Answer: 182 Btu/hr
