Consider a 1.2-m-high and 2-m-wide double-pane window consisting of two 3-mm-thick layers of glass (k=0.78W/m-°C) separated by a 12-mm-wide stagnant air space (k=0.026 W/m-°C). Determine (a) total resistance (15p) (b) the steady rate of heat transfer through this double- pane window (15p) (c) the temperature of its inner surface for a day during which the room is maintained at 24°C while the temperature of the outdoors is -5°C. (15p) Take the convection heat transfer coefficients on the 3. Glass 3 12 3 mm inner and outer surfaces of the window to be h1=10 W/m2.°C and h2=25 W/m2.0C, and disregard any heat transfer by radiation.
