A fire in a room rapidly raises the temperature of the surface of the walls and maintains them at 1000°C for a prolonged period. On the other side of one wall is a large warehouse, whose ambient temperature is normally 20°C. If the wall is solid brick, 200mm thick, and retains its integrity, what would be the steady- state temperature of the surface of the wall on the warehouse side? Assume that the thermal conductivity of the brick (ki = 0.69 W/m-K) is independent of temperature and that the convective heat transfer coefficient at the warehouse wall is 12 W/m²-K.
