2) (25 points) Consider a 1.2 m high and 2m 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 inner surface for a day during which the room is maintained at 24C 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 h =10W/mK and h=25W/m.K. There is no heat transfer by radiation
