Determine the heat flow between
the roof and floor of 4 x 3 m size
of a furnace of 4 m x 4 m x 3 m
size when the roof is at 1200 K
and the floor is maintained at 600
K, with the other surfaces non
absorbing and reradiating. The
surface emissivity of the hotter
surface is 0.8 and that of the
cooler surface 0.6.
