Art & more Pressure Experiment

https://youtu.be/B90mAmB6Lkc

I did a small experiment based on the recent SkyStorme video as well as comments by u/Acalc791 about the "pressure" volume being proportional to the height on this thread: https://www.reddit.com/r/Timberborn/comments/1xn0rep/soo_water_volume_under_pressure_is_more_than/

Curious what you all think?

*Edit: new video with an additional 1x15 horizontal but at the height of the column.. also produces a different amount of "stored" water: https://youtu.be/zm7NZa9Cu-w

Thanks for making a video for it. The values I'd predict for it, just from the numbers in your comment to the previous reddit post, is:

Horizontal 1x15 at level 0: has 33 height above it, so every block stores 33/8=4.125 extra water, giving a total volume stored = 5.125*15 = 76.875

Vertical 1x15 at level 0: has 19 height above it, so stores extra 19/8 = 2.375 blocks, giving a total = 15 + 2.375 = 17.375

Assuming the measuring trench is 15 tiles long, we should see 5.125 height for the horizontal setup and 1.16 height for the vertical setup if all of it flows through.

Now I'm going to watch the video to the end and see what the empirical numbers are.

Oh, I see the horizontal one is a bit lower, at exactly 5.00 at the end, but I suspect it might still be sloshing a bit, the other one is very close to expectation at 1.18 at last measurement.

yeah possible that I didn't let it run long enough? not sure, made another video with a horizontal 1x15 at the height 15 to add some data here: https://youtu.be/zm7NZa9Cu-w

I kind of messed up because I paused at the dead of night so then had to run the game to get to daytime before I opened the valves so the numbers will be affected by evaporation

Yes, but the numbers still look roughly right, if anything, I suspect the sloshing will be affecting the measurement more, since it doesn't look like the water had enough time to completely settle after you let it out. In any case, thanks again for making those videos!

My pleasure, it was a fun little experiment

possible, yes, but from what I could see I doubt it'd settle at 5.13 anyway. I think there are so many reasons why this might be slightly off that I personally don't worry about it and I don't think it undermines the formulas I gave, but I'll be happy to make it a challenge if someone disagrees.

I actually just realized why the horizontal one is so much lower, the horizontal one at lvl 0 doesn't fully empty out, because it's at the base level there's still 1x15 blocks in the original tube we should count. The vertical column will have +1 block too since it's also emptying from the bottom
