A 2.1 m x 0.95 m x 5.2 cm thick solid wood door has a 0.5 m square window. The window has two panes of 0.47 cm thick glass with a 0.2 cm thick space between the glass panes that is filled with argon. Argon is used since it has a thermal conductivity that is 34% lower than that of air. The inside air temperature is 18 °C and the outside temperature is -11 °C. Determine the magnitude of the heat flow through the door.
κwood = 0.10 W/(m⋅°C)
κglass = 0.84 W/(m⋅°C)
κair = 0.026 W/(m⋅°C)

1. Consider a 1.8-m high and 1.5 m-wide double-pane window consisting of two 4-mm thick layers of glass (k = 0.78 W/m°C) separated by a 10-mm wide stagnant air space (k = 0.026 W/m°C). The room is maintained at 20°C while the temperature of the outdoors is -10°C. Take the convective heat transfer coefficients on the inner and outer surfaces of the window to be 10 W/m2°C and 40 W/m2°C, respectively. Determine the steady rate of heat transfer through this...

Air has a thermal conductivity of 3 x 10-4 J cm-1 s-1 K-1. Consider a window with double panes of glass where the temperature of the inside pane is 25 oC and the temperature of the outside pane is -5 oC. The size of the window is 40 cm x 60 cm, and the panes are 8 mm apart. What is the heat flow in watts through the window? You can ignore convection.
