if one could make a classic open bottom diving bell with indestructible material, what would happen if you went several kms into the ocean?would the pressure rise inside and kill you or would it stay normal at 1 atm?what if were 5 kms deep and touched the water? would your hand get crushed?
>>16818225Your body pressurizes and nothing happens. So long as the pressure change is slow enough absolute pressure isn't an issue in any depth where water stays as liquid.
>>16818225Any bubble on the ocean will ruin your plan
>>16818227poison air coming into the bell?
You would think that the water level inside the bell would rise since gas is easily compressible, and it would be compressed to the same pressure as the water.
>>16818252Only if you believe gay shit like the ideal gas law.
>>16818252It will rise.
>>16818225your head pops off at your neck from buoyancy
>>16818252That's exactly what would happen. You would need to pump in more air as you go.
>>16818252>>16818584ok, add high pressure blowers to blower the high pressure water away and leave a comfy low pressure inner bell atmosphereproblem solved
>>16818721oops, i forgot the little blowers for the aquanaut
>>16818225google saturation diving...
>>16818584With a quick googling, there doesn't exist any maximum air pressure that would kill you. So theoretically speaking you could go to the bottom of the Mariana trench with a diving bell.The very interesting question that I would also like to know the answer to as well as the other anon, is what would happen if you then tried to go swimming in the water puddle in the diving bell. Would the super high pressure prevent you from even sinking in the water and you would just float on top of the surface? Or would the water squeeze you like a hydraulic press of sorts?
>>16818462Lost
>>16818721>the German version
>>16818225What you propose is basically a more impractical method of saturation diving, for which the generally understood human limit is 1000 meters.>https://pmc.ncbi.nlm.nih.gov/articles/PMC5110125/You will need a custom blend of gasses pumped into the bell at increasing pressure as it descends very slowly over the course of several days. Try not to need rescue btw.
>>16818721The pressure inside the bell would still be high, you would get nitrogen poisoning or something.Technically the body doesn't get crushed, but you get weird blood problems at high pressures which is what limits divers in real world diving. This can be circumvented by exotic breathing mixtures instead of air but this only gets you so far because the human body was never meant for pressures this high.
>>16818990https://en.wikipedia.org/wiki/Saturation_diving#Depth_recordsAccording to this someone was able to survive simulated pressure at 701 meters using an exotic breathing mix, maybe this could be improved on.
>>16818848Swimming would not feel any different. The water at bottom of Marianas trench is maybe 5% more dense but so will be the water inside you at that point. I do not know if you could "feel" the difference in the density, maybe you could maybe you couldn't. Perhaps it would feel bit strange when you first jump in but at just 5% the difference would be marginal and quickly lost as an active feeling I believe.>>16818990Those breathing mixtures are mostly related to non saturation diving (some exists in saturation diving too). In saturation diving you can mostly just breath regular air.
>>16818990>>16819018You'd most certainly get crushed at Mariana Trench depth.Your body can not equalize to such high pressure (1000 bar). Even if you could equalize the air in your lungs and maybe your blood vessels, your other organs would certainly be compressed. At the latest your skull would implode for not being up to the task of holding 10000 meters of water above it.If we could just equalize to the water pressure we wouldn't need pressurized submarines.
