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...
