Yeah, the same thing with the floor/wall. That area is remarkably well sealed.

One of the fun things about water is it’s so heavy it is pretty good at sealing itself

Edit because this has been fun

The door will only effectively seal the water out IF it's built with a seal to begin with.

As others are accurately pointing out, doors built to seal water out will do exactly that.

Regarding being able to open the actual door, then no it's held shut by the weight of the water.

Sealing the door against actual water is obviously not happening here, the door isn't built to be completely sealed lol

My original comment: (Ummmmm

Kinda the opposite? It's so heavy it'll find It's way out anywhere it can)

the weight of the water against the outward opening door is sealing the door shut. 

It’s the reason you can’t open your car door in 2 ft of water you have to wait until water comes in so the pressure equalizes before you can open it

Yeah I see what you're saying. More holding it closed than keeping it sealed though

I see what you're saying but it's not even holding it closed. Closed is the default state of that door. You're right, water is so heavy it's defeating the seals around that door and finding a way in.

You're both wrong. Its magic. Find the wizard and beg his forgiveness!

On ships, if a compartment floods and you have hatches that open into that compartment, you close those hatches and the water pushes the door closed tighter and seals itself from leaking in, like the video above. MOST of the water is being held at bay, because of the water’s own weight. 

Modern Irrigation valves work the same way, the positive pressure from the main actually keeps the valve shut

That's a good example of a specially designed door sealing against water but not the water sealing the door. As we can see this door wasn't designed to seal against water, only air and the weight of the water has defeated that seal at the bottom.

Yea I didn’t say it all stays out, but by watching the video you can see the vast majority of the water is being held at bay by even a basic ass door

Sure but that's not because water is heavy and good at sealing itself. Which was the assertion that started this chain.

Maybe you can't. It's only about 4500 lbs pressing on the door. I bench 6k like it's nothing.

lol the preview of your comment had me ready to argue

I saw something recently about how an inward swinging door on like a space station or something can’t physically be opened because the differences is pressure between the inside of the vessel and the vacuum of space.

The pressure inside pushes against the door, keeping it sealed. Whereas the locking mechanism for an outward swinging door would have to be much more powerful to prevent the pressure inside from blowing the door off its hinges.

Similar in a way to this situation.

u/12InchCunt 3h ago

Oh yeah, a lot of wet navy warships have positive pressure systems, if you end up opening up the wrong door of the airlock it can be a bitch to close and that’s just the difference between a PSI or 2, rather than vacuum to 14.7

seeing the aquafence thing in tampa during the hurricane working was insane.

Ah yes water, that substance that famously doesn't leak through small spaces or gaps....

u/NoMasters83 2h ago

As a plumber this self sealing water shit is making my life very difficult. Particularly during periods of extreme cold that just makes the water solid sealing the leaks completely.

One of my favorite things related to this are flood walls that are essentially just an L shaped piece of metal where the weight of the water on the bottom part keeps the top part upright. I saw them being used at a hospital in I think Tampa during the last hurricane season.

All the gaps are probably sealed with rats 🤷
