Increase gas flow speed

[Masterpintsman]

Gas rushes into vacuum as a really hight speed, according to the accepted answer on this stackexchange question with ~1700m/s.
I was curious about how the game simulation behaves and did an experiment, just for science:

Conclusion is: gas speed needs to be raised to archive somewhat realistic behaviour.

Which would also fix the issue with gas taking way to long to move from A to B to equalize pressure differences.

I suspect that there could be issues with airlocks bleeding to much pressure differential while a duplicant moves through one, or digging into a vacuum would bleed athmosphere so quickly that nothing can't be done about it - but the current situation where it can take several cycles to even out pressure differentials inside the base is imho worse.

If I had to take a guess, I'd say that the rate gases diffuse is relatively slow in order to reduce the number of gas updates per second. Awesome test though!

Raising the speed would do a few things, it would make it more dangerous to break into a pocket of gas unless you had planned a route for the gas to take to rise to the top, it would make it easier to use hydrogen as a fuel source and as the original poster said it would make bases oxygen supply function better.  It seems to move around a lot when you look at the clouds of contaminated air so I don't think there would be much of a demand on computers.

Also another related problem is when you push oxygen into a room it sits below hydrogen when it should push the hydrogen out as the oxygen pressure increases.

That actually sounds like it would improve the gameplay experience by a lot.

Yeah. I built a gas pump on one side of my space, and pipe it to a vent on the other side.

I expected there should be constant wind and I could sanitize the air through the pipe. That's what I expect to get from a pump.

But now, the part near the plumb became vacuum while the vent says overpressure. That's ... strange and I'm expecting something else.

 

One idea I think of is to assign the gas a velocity property. Maybe.
