Consider a 1.5-m-high and 2.4-m-wide double-pane window consisting of two 3-mm-thick layers of glass (k = 0.78 W/m-K) separated by a 12-mm-wide stagnant airspace (k = 0.026 W/m-K). 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 22C while the temperature of the outdoors is -5C. Take the convection heat transfer coefficients on the inner and outer surfaces of the window to be hq = 10 W/m2.K and n2 = 25 W/m2.K, respectively, and disregard any heat transfer by radiation.
