A cold storage room is constructed of an inner layer of 12.7mm of pine, a middle inner of 101.6mm of cork board, and an outer layer of 76.2mm of concrete. The wall surface temperature is 255.4 K inside the cold room and 297.1 k at the outside surface of the concrete. Thermal conductivity of pine is 0.151; corkboard 0.0433; concrete 0.762W/m-K. Calculate the heat loss in W for 1m^2 surface area. Using this formula I give to the picture.
