INSTRUCTION: Answer the question on this sheet itself, 1. A 1.2-m-high, 2-m-wide double pane window consists of 3-mm thick layers of glass (k-0.78 W/(m.C)) separated by a 12-mm-wide stagnant air space (k0.026W/(m.C)), as shown in Figure 1. The temperature of its inner surface for a day during which the room is maintained at 24C is 19C, while the temperature of the outdoors is 5C in which the outside surface of the window is at 0C. By taking the convection heat transfer coefficient on the inner and outer surfaces of the window to be h1=10W/(m2C) and h2=25W/(m2.C), the inner temperatures of the windows to be 5C and 15C respectively (=1;=5.67X108W/m2K4), determine
