A window is made up of two panes of glass (with surface temperatures of 15 oCand 5 oC) that are separated by a gap of 3 cm. The said window has a height of2 m and a width of 5 m. Initially, the gap is filled with air (flowing via temperaturegradient). Then, this air space is partially evacuated such that the pressure isalready 0.1 mpa. This is done to lessen the heat transfer between the two panes ofglass. Both glass surfaces have an emissivity of 0.9. Calculate the rate of heattransfer (W) through the panes.
