The surface temperature of a 3 ft square panel is maintained at200°F. Calculate the heat lost by the panel (a)whenattached to the ceiling, facing downwards in a room at80°F, and (b)whenattached to the floor, facing upwards in the same room. The condition through the back of the panel may be neglected. Take \epsilon = 0.9 for the panel surface.
