A furnace wall consisting of 0.20 m of fire clay brick, 0.15 m of kaolin, and a 0.05-m  outer layer of masonry brick is exposed to furnace gas at 1250 K with air at 298 K  adjacent to the outside wall. The inside and outside convective heat transfer coefficients are 55 and 10 W/m2 K, respectively. Determine the heat loss per square  meter of wall and the temperature of the outside wall surface under these conditions.
