A stable fire with an energy release rate of 600 kW occurs in a room 4m wide, 4m long and 2.6m high, with a 2.4m high door opening and 0.8 m wide. The ambient temperature is 20°C. The construction is carried out in lightweight concrete with a wall thickness of 0.15 m. Calculate the average gas temperatures in the upper layer of the room: (a) after 60 seconds (b) after 600 seconds.
