Certain wood stove designs rely exclusively on heat transfer by radiation and natural convection to the surroundings. Consider a stove that forms a cubical enclosure, Ls 1 m on a side, in a large room. The exterior walls of the stove have an emissivity of 0.8 and are at an operating temperature of Ts, s 500 K. The stove pipe, which may be assumed to be isothermal at an operating temperature of Ts, p = 400K, has a diameter of Dp = 0.25m and a height of Lp = 2m, extending from stove to ceiling. The stove is in a large room whose air and walls are at T?
