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.
GIVEN • Double glazed windows treated with low emissivity coating that reduce emissivity of uncoated surface from ?1 =0.95 to ?2= 0.5. • Temperature of glass pane 1 (T1)= 200C = 293 K • Temperature of glass plane 2 (T2) = 00C = 273 K FIND Reduction in heat transfer in coated double glazed window as compared to uncoated one. PROPERTIES AND CONSTANTS the Stephan-Boltzmann constant (?) = 5.67 × 10–8 W/(m2 K4)
