A vertical 1.5-m-high and 3.0-m-wide enclosure consists of two surfaces separated by a 0.4-m air gap at atmospheric pressure. If the surface temperatures across the air gap are measured to be 280K and 336K and the surface emissivities to be 0.15 and 0.90, determine the fraction of heat transferred through the enclosure by radiation.
