Without the hole, the space between the two panes will be pressurized. I'm not sure what the exact figures are (I'm not a phycisist) but I would guess that without the hole the outer pane will be subjected to some force F due to the presure, and the inner pane will be subjected to some force F/2, or even equal.
Without the hole the system would probably be better modeled as a single pane with an airgap between its inner and outer edges. It's likely that both panes would fail at the same time.
- darkmighty 11y agoYou don't need to be a physicist: if the panel is sealed there will be a constant pressure inside. The pressure on each face is then P_ext-P_int. It's just as likely that both panels will fail at the same time in that case as in the case with a hole; but the bonus in this case is that you can set up the internal pressure so both panels have lower nominal pressure (but the internal at least should be able to still handle the full pressure difference). I know it's routine to manufacture even household glass panels with different gases sealed in their interior (I think they put Argon inside? some low conductivity gas), but afaik it's at atmospheric pressure.
