Wouldn't this human in theory become a crumpled sausage like what happened to the crab by the leaking underwater pipe?

This really Byfords my Dolphin
Wtf is a psi
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
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.

The biggest problem is he's engineering in Imperial instead of SI units.

But where's Saddam?
This unfortunately happened in real life.
Edit: other way around though. The divers were on the air side (habitable quarters) of the chamber.
For more clarification, they were on the high pressure air side. The kind of dives they were doing involved long periods of acclimation to the different pressures involved, so the diving bell was pressurized to 9 atmospheres. Someone fucked up, and the door opened. 9 atmospheres turned into 1 atmosphere very quickly, and the only good thing is that it happened so fast that the deceased wouldn't have even noticed
If you want to see an episode of a podcast about engineering disasters which is itself, ironically, an engineering disaster, well there's your problem
Just for what it’s worth, it looks like it was actually an equipment malfunction, not someone fucking up, that caused the accident. The company claimed the person fucked it in an attempt to cover their asses, and they were eventually found to be hiding the truth in a court of law.

No one fucked up, they finally settled on it being a mechanical failure.
Edit: the company and government fucked up, I meant to imply none of the divers fucked up.
The company fucked up, they did not maintain their equipment.
The company fucked up by not updating their equipment, even though they knew it was outdated and dangerous
“The North Sea Divers Alliance, formed by early North Sea divers and the relatives of those killed, continued to press for further investigation and, in February 2008, obtained a report that indicated the real cause was faulty equipment. Clare Lucas, daughter of Roy Lucas, said: "I would go so far as to say that the Norwegian Government murdered my father because they knew that they were diving with an unsafe decompression chamber."[11] The families of the divers eventually received compensation for the damages from the Norwegian government, 26 years after the incident.[12]”

I'm unfamiliar with fluid dynamics. How intense would the Delta p problem be in this situation?
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...
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.

Big succ P
Is this like the end of that Aliens movie?
Water go sluuuurp, human go squish.
Chunky marinara factory.
Only the Byford Dolphin ruduces an entire diver to a soup-like homogenate in 30 seconds
When it’s got ya, it’s got ya.
Am I assuming correctly that we're looking at a big succ-situation, where the diver will big forced through the tube no matter what?
It's a difference of like 7 psi over an area of what looks like maybe 30 square inches, which would be uncomfortable to get caught in, but I don't think you're getting Byford Dolphined
210 lbs will certainly keep you stuck there though
Ahhh yeah that's where I've heard it before, WTYP had an episode on that!

Is 5m enough for that? I feel like no, but i have no idea.
Yup.
Do NOT put your dick or butthole there
Well if you have both, and disregard this warning, it will be hard to separate the two
