Consider a 0.8 -m-high and 1.5 -m-wide double-pane window consisting of two 4 -mm-thick layers of glass (k=0.78W/mK) separated by a 10mm-wide stagnant airspace (k=0.026W/mK). Determine the steady rate of heat transfer through this double-pane window and the temperature of its inner surface for a day during which the room is maintained at 20C while the temperature of the outdoors is 10C. Take the convection heat transfer coefficients on the inner and outer surfaces of the window to be h1=10W/m2K and h2=40W/m2K, which includes the effects of radiation
