A furnace wall is made up of a steel plate 10 mm thick. The steel plate is lined on the inside with silica bricks 150 mm thick. Likewise, on the outside, the steel plate is lined with magnesia bricks 150 mm thick. The surface temperature of the inner wall is 700°C. The surface temperature of the outer wall is 150°C. Determine the temperature at the interface of steel and magnesia brick. The thermal conductivity of steel, silica brick and magnesia brick are 16.86 W/m.K, 1.75W/m.K, and 5.23 W/m.K respectively.
