Consider a single pane glass window that has an area of 8ft^2and is 3/16†thick. The outside temperature is -10oC and the insidetemperature is 21oC. [9]
a.How much heat flows through the window in 8 hours? Use anR-value.
b. In reality, all surfaces have a thin layer of air coveringthem that does not move. This air“film†is about .0005m thick.Calculate how much heat flows through the window in the 8 hourperiod with the addition of this film of air on both sides of thewindow
Most windows are double-pane glass with ½†Argon gas between thetwo panes. If the R-value of Argon gas is 0.54 W^-1 •m2•oC for athickness 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
