CoursHeroTranscribedText: 2. A vertical 1.5 m high and 3 m wide double pane window consists of two sheets of gless separated by= 1.5 cm thick air gap. In order to reduce heat transfer through the window, the air space between the two glasses is partially evacuated to 0.3 atmosphere pressure. The emissivity of the gloss surfaces is 0.9. Taking the gloss surface temperatures across the air gap to be 15 deg C and 5 deg C, determine the heat transfer through the window by natural convection and radiation. Fig. 02 Assignment B
