A Thermopane window consists of two glass panes, each 0.50 cm thick, with a 1.0 cm thick sealed layer of air between. If the inside temperature is 23.5°C and the outside temperature is 0.0°C, determine the rate of heat transfer through 2.0 m2 of the window. Compare this with the rate of heat transfer through 2.0 m2 of a single 1.0 cm thick pane of glass. J/s (Thermopane window) J/s (Single pane window)

Heat Transfer
Problems 1. A window pane (1/8 inch thick) in an old house owned by a professor is 3 ft. by 4 ft. He likes to be warm in the winter so the inside temperature is kept at 70 °F even when the outside temperature is 10 •F. For this problem assume the inside and outside temperatures are for the window surface. How much heat is transferred through the window (k=.54 BTU/hr ft ° F)? 2. A small heated...

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...

A Thermopane window consists of two glass panes, each 0.50 cm thick, with a 1.0 cm thick sealed layer of air between. If the inside temperature is 22.0°C and the outside temperature is 0.0°C, determine the rate of heat transfer through 1.0 m2 of the window. Compare this with the rate of heat transfer through 1.0 m2 of a single 1.0 cm thick pane of glass.
