I have no clue what any of this means, yet I laughed.

That man is gonna go through that pipe and become spaghetti
2137 (and a half)!
I don't get it:
21 psi ~= 1.4 bar
15 feet ~= 4.5 m
To reach 1 bar pressure you need ~10m of water no?
Depends. They are probably meaning 0.4 bar greater than the pressure at the surface which is approximately 1 bar
To get one bar more than at the surface you need ten metres
What's the formula for this?
F=Δp⋅A
I’ll never forget this video of a crab being sucked into a pipe being cut or this one of a diver in a similar situation.
Damn ._.
It's harder to get that second link by people these days. Previews.
Also we know the URL by now
I click it voluntarily. Its a good song
10/10 no notes
an oldie but a goody
Physics is a cruel mistress.
Can someone please explain the reference to me?
guys ! don't stick your butthole near the pool drain pipe
no matter how good you think it might feel on your butt.

Bro is about to be sucked into the opening and mangled to death then drown because of the flow / pressure / whatever
Delta-P
It would not let them go once attached but sucking through? If the hole is 10cm in diameter i would think it wouldn't rip them apart.
But let's physics this please!
Let's do it:
The phenomenon that causes divers to be trapped is called differential pressure, or Delta P. It requires surprisingly little Delta P to trap divers in such a way that they can't free themselves.
The formula is simple: F=Δp⋅A
Δp = Differential pressure, A = the area the differential pressure acts on, in our case the cross sectional area of the pipe.
Example:
30 cm pipe => A = π⋅(0,15)² m²
Delta P only (!!!) 0.1 bar (= 10 kPa).
F = 10,000 Pa ⋅ 0.07 m² ≈ 700 N. This equals roughly 71 kg of weight.
Now, let's try this with the numbers above. Unfortunately, we don't know the diameter of the pipe so let's again assume 30 cm:
Δp = 21.375 - 14.7 psi = 6.675 psi ≈ 0.46 bar = 46 kPA
F = 46,000 Pa ⋅ 0.07 m² ≈ 3250 N.
=> You would be sucked to this pipe opening with a force of roughly 330 kg. In other words, you're fucked.
For fun, let's assume a 50 cm diameter pipe:
F = 46,000 Pa ⋅ 0.196 m² ≈ 9020 N.
This equals roughly 920 kg of weight.
=> There is absolutely no escape here and I think it's safe to assume the diver would be sucked through that pipe.
And finally, to answer your question (I'll skip the math here), a 10 cm diameter pipe with the same Delta P would mean 37 kg of weight. I think it would be possible to escape in this scenario, but it'll not be effortless.
i remember a greentext about this, and a wiki article, but where is it again? I thought it was the Norwegian oil platform disaster but no
there was some talk about how they got discombobulated and their bodies had gross dismemberment or something, being entirely suctioned through
edit: aha, found the article!
the causes:
- employees were overworked
- bad audio and noise caused miscommunication
- entry/exit door was unsafely designed
Colourful NSFW description ahead
Investigation by forensic pathologists determined that Hellevik, being exposed to the highest pressure gradient and in the process of moving to secure the inner door, was forced through the crescent-shaped opening measuring 60 centimetres long created by the jammed interior trunk door. With the escaping air and pressure, gross dismemberment ensued; it included bisection of his thoracoabdominal cavity, which resulted in fragmentation of his body, followed by expulsion of all of the internal organs of his chest and abdomen, except the trachea and a section of small intestine. These were projected some distance from the bell, with one section being found 10 metres vertically above the exterior pressure door.

Delta P doesn't care. Delta P doesn't give a shit.
Don't know about you, but I never take a shit without my Delta_P! Thanks Delta_P!

I mean the dolphin story is gruesome. But for this diver to get a severe injury he must be very close to the hole, almost touching it.
The suction power is not that great in an underwater scenario.
What made the dolphin so gruesome is that it was an explosive decompression and besides the driver closest to the door no server dismemberment took place, only a very sudden decompression making for a very sudden yet horrid death.
If the diver in this diagram keeps a couple of centimeters away from the opening he is completely fine but if he manages to cover the outlet hole with some of his anatomy, the shit hits the fan.
Sooooo ... Don't put your dick in it, yeah?
How about a small cylinder? The cylinder must remain unharmed though
Just near it enough to get a little suction
