A building is totally involved in fire, but there is no external flaming. One wall, measuring 20 m long by 10 m high, has four symmetrically placed windows, each 6 m long by 2 m high (see figure below). Assuming that the windows act as black- body radiators at 1000°C, calculate the radiant heat flux 10m from the building, where the radiant heat flux is a maximum. Assume that the receiver is parallel to the face of the building. A building is totally involved in fire, but there is no external flaming.
