101 kPa

[Ext.]

so I did a test and evaporating 128 oxides in a 3x3 by 1 height gives precisely 101kPa so that I can breath with the helmet opened.

for larger room, do you require more oxides? I currently do not have a large room to test.

More volume would indeed require more gas to keep pressurised at the same level. That's why there's mol as a measure in the game, because it's a measure of density (simplest way to describe what mol measures), instead of litres (which is a measure of volume, and a gas can be 1Kpa or 1Mpa and take up 1 litre of volume, because gases can be compressed).

i got 2 connected rooms with 3x4x1 and 4x5x2 and i dumped 850 oxite in my Arc Furnace and i got 121 kPa pressure... so yeah you need alot more ^^

after i managed to rise the temperature from 0.2°C to 17°C one of my window glass sheets decided to go AWOL... so .... shame on me :) anything above 235 kPa within a closed space requires fully upgraded steelframes and support frames and double airlock..

with this i managed to pressurize a room at 350kPa for no reason at all....

The question is how much pressure can be in a room?

200 kPa is the limit for rooms with windows
Wall - Not Tested
Double Windows (placed within and another on the outside) - Not Tested
Double Wall - Not Tested

To that end. I build a room 3x3x3 all solid Steel Frames and left out the one in middle. Pressure Sensor, Active Vent for release and Passive Vent + Volume Pump for Input.

I reached 22000 kPa so far and still no pressure lost. I'm out of gas. The little room literally eat two 10 MPa Small Tanks with 25000 Mole each + all Pipe Network Contents ... and did not break so far. I'm out of gas so I don't know where it ends. I really would like to know how many mole are in there now, but the pressure sensor does not provide the mole amounts.

So If you need a Super-Large Volume Tank Build a Solid Steel Frame Tank for it.

Of course it's not possible to go in there, just opening it may push you into orbit. Mmmm ... intresting idea ...

EDIT: Cool I release the one frame at the top by one level ... pushed me roughly 50 frames into the air like a human cannonball. Too bad it's one time only I never get enough gas together again.

EDIT 2: I activated the Jet Pack in Orbit ... now I can see everything from far above a tad longer.

EDIT 3: If you are fast enough you can build something below you and basically have a space station. But you can build from ground into orbit as well of course.

I have a 3x2(internal volume) gas chamber and 150 ore creates approx 160 kPa. So the room volume does play a part.

yeah. using algebra makes it easy figuring out the correct amount of mineral to use to have desired pressure.
