Compute the ratio of the rate of heat loss through a single-pane window with area 0.15 m2 to that for a double-pane window with the same area. The glass of a single pane is 4.4 mm thick, and the air space between the two panes of the double-pane window is 6.50 mm thick. The glass has thermal conductivity 0.80 W/m⋅K. The air films on the room and outdoor surfaces of either window have a combined thermal resistance of 0.15 m2⋅K/W

Consider
the rate of heat conduction through a double-paned window that has
a 1.45-m2 area and is made of two panes of
0.715-cm-thick glass separated by a 1.25-cm air gap. You can ignore
the increased heat transfer in the air gap due to convection.
Calculate the rate of heat conduction through this window, in
watts, given that the inside surface temperature is 15.0°C, while
the outside temperature is -10.0°C. Make the assumption that the
temperature differences across the two glass...

To reduce building heating costs, modern building codes in many parts of the country require the use of double-pane windows (sometimes, called "double-glazed" or "thermopane" windows). Ivpically, a double-pane window consists of two panes of glass separated by a space that contains trapped stagnant air. In one design of a double-pane window, each glass layer is 0.7 cm thick, the stagnant air layer is 2 cm thick, and the area is 4 m2 In the living room of a large...

(a) Calculate the rate of heat conduction (in W) through a double-paned window that has a 5.00 m2 area and is made of two panes of 0.700 cm thick glass separated by a 1.00 cm air gap. The inside surface temperature is 17.0°C, while that on the outside is −20.0°C. (Hint: There are identical temperature drops across the two glass panes. First find these and then the temperature drop across the air gap. This problem ignores the increased heat transfer...

Which of the following two windows would insulate better, and by how many times lower would the rate of thermal conduction through it be compared to the other? Take both to be airtight and ignore radiative losses. Each window has a total size of 1.2 m high by 0.6 m wide, with the outer 2 cm edge of each window being the frame. For simplicity, take the frames to have the same thickness as the glass. For the first window,...
