3 4. (30 pts) radiation; a cubical room 3 mx 3 mx 3 m is heated through the floor by maintaining it at a uniform temperature of 310K. Since the side walls are well insulated, the heat loss through them can be considered negligible. The heat loss takes place through the ceiling, which is maintained at 280K. All surfaces have an emissivity & =0.85. Answer each following question: Long #2 (50 min) ceiling Az = 9 м2 Tz = 280k...
