Estimate the heat loss, due to conduction through a 1 square meter window if the inside temperature is 20°C and the outside temperature is 0°C. There is a stagnant layer of air on each side of the window, which makes the temperature difference across the 5 mm thick window only 1°C. This answer was 160 W. Estimate the heat loss by conduction through if it is double paned. Assume the stagnant air layer is between the two layers of glass...

A wall in a house contains a single window. The window consists of a single pane of glass whose area is 0.15 m2 and whose thickness is 1.9 mm. Treat the wall as a slab of the insulating material Styrofoam whose area and thickness are 15.00 m2 and 0.110 m, respectively. Heat is lost via conduction through the wall and the window. The temperature difference between the inside and outside is the same for the wall and the window. Of...
