In order to conserve energy, the inner surface of double-glazed windows are treated with a low emissivity
Question:
In order to conserve energy, the inner surface of double-glazed windows are treated with a low emissivity coating that reduces the emissivity of the
uncoated surface from 0.95 to 0.5 for the coated surface. If the temperatures of the two glass panes are 20°C and 0°C, respectively, determine the reduction
in heat transfer in a coated double-glazed window as compared with the uncoated one.
