The windows on the Apollo Command Module were double-paned tempered silica glass with an additional amorphous-fused silicon layer outside. Consider the heat flow through one of these windows as though it was a regular double-paned window that we use down here on Earth. A side window on the Apollo command module was a 15-in × 15-in square, consisting of two layers of glass separated by 0.05-in of air. Neglect the heat flow through the glass, and only consider the heat flow through the thickness of the air. What is the heat flow through this window over a span of 4.00 hours, given that the temperature inside the command module is kept at a constant 22.1◦C and the temperature of outer space is −545◦F?
