I don’t see the problem.
I mean, I don’t swim, but the dynamics seem to make sense.
What am I missing?
Edit: Ah, don’t go near the water passage, right?

I just remembered that meme “SpongeBob Experiences Delta-P and Dies Instantly”
Although I’m having a Mandela Effect moment where I swear I saw a version where Patrick talked a lot longer with much more technical information.

Like that, but with people.
Ouch!
And just to think, we’re all gradually evolving into crabs…
no we’re not carcinisation is a vastly overblown meme it’s other crustaceans in similar environments evolving into crab like forms as they already fill the same ecological niche and a crab body is perfect for that ecological niche any other creature is not evolving into crabs I hate the carcinisation meme
Chunky marinara factory.
Only the Byford Dolphin ruduces an entire diver to a soup-like homogenate in 30 seconds
Water go sluuuurp, human go squish.

Top 10 ∆P incidents
Wtf is a psi
It’s the Imperial Gangnam Style unit
It’s what you need to power your Protoss army
Muricas version of pressure.
Freedom units
It would kill you regardless of where you live
100.000 PSI is equal to 1 bar(if I remember correctly)
That’s metric
Unfortunately no, 1 bar (1 atmosphere) is 100,000 pascal
PSI is pounds per square inch and is roughly 14.5 PSI to 1 bar, and to me, way less intuitive than bar
PSI is a nice scale for tire pressure since most tires will be between 20-100 PSI. There’s pretty much never a reason to use decimals, and 5 PSI is the most useful increment.
Bar is probably nicer for a bunch of other things, but for everyday use, PSI has a nice scale. That’s also why I prefer Fahrenheit to Celcius for weather, but Celcius for cooking and science.
Ah thanks.
no, not at all. bar is a logical metric unit, psi is imperial. because the us doesn’t know what powers of 10 are, there’s never a nice conversion factor.
US uses both and is capable of conversion. It is unfortunate, but saying it doesn’t know powers of ten is pretty condescending.
I said (or at least meant) that imperial doesn’t use powers of ten like metrkc
Word. “The us doesn’t know what powers of 10 are” just didn’t convey that clearly.
We’re stuck with this shit for now, and one of the few positive things is that it forces you to understand both the conversions and power of 10 is cake compared to understanding both and converting.
pounds per square inch. the us version of bar or n/m²
Why is your comment highlighted blue in Lemmy Connect?
DELTA P 🗣️🗣️
Do NOT put your dick or butthole there
Big ‘Guts’ vibes here
Well if you have both, and disregard this warning, it will be hard to separate the two
The biggest problem is he’s engineering in Imperial instead of SI units.
I thought the same way, then became an American engineer. Fuck a horsepower, because it’s so goddamned context dependent.
I’m unfamiliar with fluid dynamics. How intense would the Delta p problem be in this situation?
I feel like a delta of less than 10 psi doesn’t sound so bad
It depends on the size of the opening. If it’s small that’s no problem. You could block a 1 inch pipe at 10psi with your bare hand and be largely fine. It’s a little less than 10 pounds of force assuming a round opening.
The problem is that the total force scales geometrically with the size of the opening. Make it two feet wide at the same 10psi and now you’ve got about 4500 pounds of force trying to push you though that opening should you find yourself in the unfortunate situation that it’s been completely blocked by your body.
Yes. As long as the pressure is not enough to put a hole in you, you just need to care about the force.
Yeah fair play to the big opening issue, I was picturing 1-20cm holes
Yeah, the rendering shows it to be about the height of a foot. So probably not too bad.
Big succ P
Soup like homogenate
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 (24 in) 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, and of the thoracic spine. These were projected some distance from the bell, with one section being found 10 metres (30 ft) vertically above the exterior pressure door.
Soup indeed.
a section of small intestine
Huh. Weird. I wonder why that stayed in place. I mean, I wouldn’t have thought that you can squeeze out a person like a tube of toothpaste but since that is apparently a thing…
When it’s got ya, it’s got ya.
Yeah I read about it. Definitely not the nicest way to go.
is it just me or does this look like the cover of You Would Rather an Astronaut?
Danger Zone!
Is this like the end of that Aliens movie?
