5. Consider a 1.2-m-high and 2-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 air space (k = 0.026 W/m K). Determine the steady rate of heat transfer through this double-pane window and the temperature of its outer surface for a day during which the room is maintained at 24C 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 hi = 10 W/m2-K and hz = 25 W/m2- K, and disregard any heat transfer by radiation.
