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 3-cm-wide air space. Determine the steady rate of heat transfer through this window and the temperature of its inner surface for a day during which the room is maintained at 200C while the temperature of the outdoor is 00C. Take the heat transfer coefficients on the inner and outer surfaces of the widow to be h1 = 10 W/m2 .K and h2 = 25 W/m2 .K and disregard any heat transfer by radiation. Evaluate air properties at a film temperature of 100C and 1 atm pressure. Is this good assumption? [Ans.: 64.9 W]
