Calculate the decrease in heat loss in kilowatt-hours per day when a 1.2 m x 2.1 m uncoated single-pane window is replaced with a double-glazed window with a low-e coating and argon fill (a relatively common configuration for current win- dows). The inside temperature is a constant 20°C, and the outside temperature is a constant -5°C.

A dual-pane window in a house is composed of two parallel panes of glass, each with an area of 2.23 m². Each pane of glass is 3.10 mm thick and the space between the panes is 12.5 mm thick and is filled with argon. (a) Calculate the heat flow through the window if the indoor temperature is 18.3°C and the outdoor temperature is -20.6°C (this is about -5°F). (b) Determine the temperature on the inside of the pane (this is in the argon-dilled region) closest to the outside of the house.
