A double-glazed window is 1.3 m high and 0.7 m wide. The space between the glass plates making the double-glazed window, which is 2 mm thick, is filled with atmospheric air. Calculate the rate of heat loss through the window when the two glass surfaces are at 10 ◦C and −10 ◦C. Neglect the contribution of radiation heat transfer.
