consider a 0.8-m-long and 1.5-m-wide double-pane window consisting of two 4-mm-thick layers of slass (k=0.78) separated by a 10-mm-wide stagnant air space().determine the steady rate of 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 oudoor is -10C. Take the conection heat transfer coefficientss on the inner and outer surfaces of the window to be h=10 and h=40 which includes the effects of radiation.
