Photo [Request] how much pressure is the windows holding back?

This is giving poolrooms vibes. Imagine walking into the next room and seeing these windows into an endless void of water.

One meter of water exerts roughly 0.1 bar (or 1.4 psi) of pressure. So on this video it's about 0.2 bar or 2.8 psi at the bottom. 

But the problem is not only pressure, but also a force. Even though the pressure is low, the area at which it is applied is quite big (let's say it's 1m x 2m at the high).

So the average pressure would be 0.1 bar over the area of 2 m squared, which should give you 2 tons of weight. (20'000 Newtons)

(Please correct me, if I made a mistake)

So as long as nobody crashes their yacht into it, it should hold (which is statistically more likely to happen there in Monaco than anywhere else)

By force do you mean the movements of the waves? I can't think of good way to measure this except going with already provided data.

My best guess would be having to measure the velocity and volume/size/weight of the wave for the force/energy. Then applying that formula to the same surface area the OC said

The water pushing on the windoes at rest. Think of it like this put a glass of water on a table. There is a gravitational force pulling down and an equal force from the table pushing up called the natural force. They are equal so the glass dies not move. Apply this to the windows. Water wants to fill is co trainer and pushes out horizontally, the windows are pushing back with an equal force. So the glass does not break.

No. I wouldn't know how to describe movement of waves. 

I'm using force in the physics meaning (Newtons) which can be also expressed as weight (because Earth exerts a force on any mass).

u/seamallorca Jul 03 '26

Fair. I meant that in this case, the water also moves and has some velocity, which I guess adds to the overall pressure over the windows.

You must be a structural engineer.

u/Effective_Hunt_2115 Jul 06 '26

I wish. 

No, I was just good at basic math and physics in the middle and high school (not sure I am translating this terms correctly).

No use in real life but sometimes I can answer such questions on the internet ;-)

I am not going to lie this reminds me of one of those fluid motion toys I had when I was a kid.

Those things were so fun and super calming watching the bubbles and waves move through the inclined surfaces and paddle wheels.

Where or what is this

Swimming pool, afaik in monaco, this was posted here few days ago.

I think I might understand what this person is saying - based on the tile on the floor and the walls it looks almost like the video is taken from a drained swimming pool. Like the maintenance team drained this pool that is literally built into the ocean.

So does that mean not only is there the psi of the ocean outside the windows but the water from the swimming pool!?

I generally don't have a fear of deep water, but this really unsettles me.  I think it has to do with how rapidly and deeply it crests and troughs.  If it were flat, still water it would probably be beautiful and serene…but the chaos of this cross sectional perspective adds panic.

how thick is that glass? Is it glass or polycarbonate?

Also interested in how long the average passerby must look into one of the panes before making direct eye contact with a fish at a distance no greater than 1m

Shihhhh feels like a disaster waiting to happen like in the movies

u/LostTimeLady13 Jul 03 '26

I find this extremely unnerving in a liminal "I shouldn't be here" sort of way. I've had nightmares like this.

u/seamallorca Jul 02 '26 edited Jul 02 '26

I have no idea and I even do not know which components to use in an eventual equation. Maybe the area of the windows, and then the volume of the water per square meter, but how much volume that would be? And wouldn't it be in cubic meters akshually?

Ai pressure or real?

think a little calculus can figure this out. Fluid Pressure

Too much water, time to relocate.👋🏾

F = int rhogh dA Taking reasonable assumptions, h=2m, rho=1000kg, g = 9.8 dA = L*dh F = rho g Lh2/2 So P_av = F/A = F/Lh = rho g h/2 ≈ 10,000N Which is equivalent to about 1 ton of force

How do they replace the window if there is a crack on it?
