Probably combusted? At 400 atms their biomass would compress into a gelatinous hydrocarbon fat blob with the oxygen present, resulting in automatic combustion.

Probably combusted? At 400 atms their biomass would compress into a gelatinous hydrocarbon fat blob with the oxygen present, resulting in automatic combustion. The amount of compression their bodies would experience is an order of magnitude greater than a diesel engine cylinder. The explosion would immediately be quenched by the surrounding water and the only thing remaining of the occupants would be ash.
This would happen on the order of milliseconds.
- pfdietz 3y agoAdiabatic compression of air to 400 bar increases the absolute temperature by about a factor of 5.5, which would be the temperature of a flame.
- amluto 3y agoWater, fat, etc are not nearly as compressible as air, and the thermal mass of the air involved would be a couple orders of magnitude lower than everything else. 400 bar is (from some quick searching) fairly mild for industrial hydraulic systems, and hydraulic fluid doesn’t get especially hot while in use. On the other hand, a leak in a pressurized hydraulic system is extremely dangerous if you’re around it due to the extreme velocity of ejected fluid.
- f38zf5vdt 3y agoHydraulics don't get hot while in use unless you introduce air into the system, in which case they do get hot and explosive. This is called hydraulic dieseling and microdieseling. The passengers would have been surrounded by oxygen and CO2 gas, and the oxygen tank would rupture as soon as the capsule imploded.
- jamiek88 3y agoWhen it happened in that accident referred to elsewhere in the thread the water temp was elevated massively in that area (enclosed so measurable). Their blood would combust instantly. They found cooked blood after that accident too. Edit: https://en.wikipedia.org/wiki/Byford_Dolphin https://en.wikipedia.org/wiki/Byford_Dolphin
- f38zf5vdt 3y agoThat accident was only 132 psi. A diesel engine causes combustion at around 300-500 psi. This accident was 3000-6000 psi, so I think it's safe to assume that the organic matter would combust almost instantly.
- amluto 3y agoWhy would anything, except possibly something particularly easy to ignite on a surface, ignite? The only thing being heated dramatically is the air, and a whole lot of cool water would be spraying everywhere at the same time.
- jamiek88 3y agoSame way bubbles imploding have localised temps hotter than the sun, just that writ larger and at 400 times atmosphere. This: https://www.dailyrecord.co.uk/news/uk-world-news/divers-blood-boiled-rig-incident-24430481 https://www.dailyrecord.co.uk/news/uk-world-news/divers-bloo... was 'only' at nine atmospheres the titanic is at four hundred!
- ilyt 3y agoWent to see titanic only to get turned into diesel, horrible fate
- babypuncher 3y agoSomeone put Mythbusters on the case
- pugworthy 3y agoThey sorta did one like this ... https://www.youtube.com/watch?v=LEY3fN4N3D8 https://www.youtube.com/watch?v=LEY3fN4N3D8
- f38zf5vdt 3y agoYeah, it would be curious (if morbid) to see what happens to something like an animal carcass. In most cases of submarine failure at depth e.g. the USS Scorpion no bodies are ever found.
