Physics question

I've got a question for all you brainiacs - how would you calculate
the wind velocity of a window panel blowing out in a Habitat?

I'll leave it to you to assume the window dimensions and other
factors.

I got to thinking about the process of replacing the window panel
and thought that the crew will have to be working in a turbulent
vortex as they manoeuver the surface area of the replacement window
into place.

Follow-up question - what would be your preferred process for window
replacement? Secure from inside the Habitat or from outside?
