Consider a single pane glass window that has an area of 8ft^2 and is 3/16” thick. The outside temperature is -10oC and the inside temperature is 21oC. [9]

a.How much heat flows through the window in 8 hours? Use an R-value.

b. In reality, all surfaces have a thin layer of air covering them that does not move. This air“film” is about .0005m thick. Calculate how much heat flows through the window in the 8 hour period with the addition of this film of air on both sides of the window

Most windows are double-pane glass with ½” Argon gas between the two panes. If the R-value of Argon gas is 0.54 W^-1 •m2•oC for a thickness of 1 cm, find:

i.The effective RSI-value of the window.

ii.The effective R-value of the window.

iii.The effective U -value of the window

A wall in a house contains a single window. The window consists of a single pane of glass whose area is 0.16m^2 and whose thickness is 2.0 mm. Treat the wall as a slab of the insulating material styrofoam whose are and thickness are 18m ^ 2 and 0.10 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...
