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

[–] starman2112 22 points 1 week ago (7 children)

Not at 15 feet. I don't know enough to say how fast the water would be leaving that hole, but it's maybe a couple hundred pounds of pressure. If he even got caught, it would be super uncomfortable, but he ain't about to get ∆p'd

If you wanna see a real crab-in-a-pipe situation, look up that Byford Dolphin everyone's talking about

[–] [email protected] 4 points 1 week ago (4 children)

Yeah I read the entire Wikipedia entry on the Byford Dolphin and I almost threw up because how vivid the description is. I think this would be my third time saying this but that's not a nice way to go (to die) at all.

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

from the wiki

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

[–] [email protected] 18 points 1 week ago (2 children)

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.

Yeah fair play to the big opening issue, I was picturing 1-20cm holes

Well if you have both, and disregard this warning, it will be hard to separate the two

Yeah I read about it. Definitely not the nicest way to go.

Only the Byford Dolphin ruduces an entire diver to a soup-like homogenate in 30 seconds
