100sqft wormhole from sea level to outer space?

[shintashi]

TL;DR

Assuming the difference in pressure of say, 100km up in space, and a portal 10x10, what would the wind speed be near the wormhole/portal?

Hypothetical scenario and I'm trying to understand the velocity of the air as it tries to equalize with a large vacuum. I presume this model isn't very much different from an initial loss of 1 atmosphere pressure in space via some puncture. I'm mainly concerned with the immediate wind speeds and possible influence on weather. The model isn't intended to be sustained for more than 60 seconds so "draining the atmosphere/oceans" isn't what I'm looking for, and statistically, while I don't know what the wind speed might be for a 100 square foot hole (circle or square) I do know the volume of Atmosphere is so high that the total impact of a 60 second hole would be negligible on displacing its whole mass.

Again, I just want I know how fast the air would flow through the hole.

Depends on unknowable physics of your wormhole.

Do you basically want to know what happens if you have a wall separating a very very large volume of air at atmospheric pressure from a very very large evacuated volume, and you open a hole in the wall? That's answerable. The wormhole one isn't, really.

It sounds like you are writing a SF story. Is that correct?

If this is just a very tall tube, the answer is zero.

The wormhole one isn't, really.

Would it be acceptable to say that it doesn't make a perpetuum mobile possible?

I wouldn't make any statements at all about an unspecified spacetime. From the point of view of PF rules, one would hope you are right...
