15.21 The cross section of a storm window is shown in the sketch. How much heat will be lost through a window measuring

1.83m

by

3.66m

on a cold day when the inside and outside air temperatures are, respectively, 295 and

250K

? Convective coefficients on the inside and outside surfaces of the window are 20 and

15(W)/(m^(2))*K

, respectively. What temperature drop will exist across each of the glass panes? What will be the average temperature of the air between the glass panes?
