anon's in trouble because they're using psi instead of bar.
Edit: also fuck high pressures are a scary thing.

We have mmHg at home (feet water)

is it just me or does this look like the cover of You Would Rather an Astronaut?
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.
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
If you were on your back and had your legs above the hole, is 7 psi strong enough that you wouldn't be able to fight it?
I guess another question would be "how strong would it be compared to gravity?" (if anybody has any idea)
It very much depends on the size of the hole. 7 psi over 1 square inch is 7 lbs, but the same pressure over 100 square inches is 700 lbs.
For a naive estimate, the hole looks around 6 inches wide, which gives it an area of around 30 square inches, so there's like 200 lbs of water pressure over the area of the hole. An even more naive assumption is that if you were "standing" over the hole in the wall, you would feel 200 lbs of pressure forcing you "down," which I think most people could easily handle. I'm doing more than that right now!
Unfortunately I don't know how to even start to calculate the force of the water on you as it rushes past you, but my gut instinct is that it wouldn't be more than the total pressure in the hole

This unfortunately happened in real life.
Edit: other way around though. The divers were on the air side (habitable quarters) of the chamber.
The families of the divers eventually received compensation for the damages from the Norwegian government, 26 years after the incident.
Well, it's good that some justice was finally achieved, but that is depressing level of covering up (as usual)
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

But where's Saddam?
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.
