How does a submarine sink and rise ? Animation

A short animation of how a submarine can sink, float and rise by using its ballast tanks

[@ZVEKOfficial]

I cant believe I had to watch 10 other videos before I stumbled upon this one that ACTUALLY explains how a submarine dives and resurfaces!!

Same lol. I've been trying to figure out how they work for 45 minutes but now I'm not sure I can bear to hear this dudes voice long enough to hear the actual answer

Compressed air part is so important

[@christophertadeo6120]

So for a drone to be all-purpose u need a ballast that can controllably contain helium not just ordinary air while inflight and then take in water while it's beneath the surface... 🤔

[@966Mako]

I still want to know where the compressed air comes from, there's not an endless supply. Are they topped up when surface running, like filling a scuba tank. Iv never understood why the expelled air isn't sucked out into a storage tank to be reused, instead of just escaping into the atmosphere. Thanks for posting, but I still have questions that need answering. 👍🏼👍🏼

[@utkarshsodagar2674]

Just saw this video tonight. I would try to answer according to my perception. As far as compressed air is concerned, there should be two ways of storing it. 1) by pre-installed air compression storage before submarine to launch in sea. 2) while the submarine is floating over surface. Here, one rotor should be mounted on engine shaft to suck the atmospheric air through long pipe over centre-head of submarine. Here, I think certain amount of water is to be stored before operation and that would successively drain out with suction of atmospheric air. This should be provided to make mass balance else submarine would not glide over surface ( could start to imbalance. However, chances are i very small because density of air is very less to imbalance such heavy weight body.)Just added to this not to prove 1st law of Energy conservation wrong. Haha. However, for your second argument of expelling of compressed air along with resuction and storage of same for reuse, I would say it is not possible. Since compressed air is allowed to drain water out to rise submarine. Here, one thing should be kept in mind that while submarine is completely submerged you could not suck the air. As there is no scope to suck as that long pipe over centre-head of submarine is also under water. Entry of fluid must be closed through it otherwise it would only allow water to fill in which is total non-sense of forcing water drain from one side and allowing it to suck in from other. This could not allow submarine to sufficiently rise. Here, no air could be sucked at all only the water could. Hope my answer is satisfactory as I also applied my thoughts.

[@muhindomoses8735]

I have now take 9 year am writing theories on how submarine dive and suface from 2011 now is 2019, i got some correct and soon I will be a manufacturer of submarine

[@nokaoemauibuilt]

This video is wrong. They aren’t refilling the tank with air, they are pumping water in and out to change the buoyancy force of the sub. Volume of air remains the same but is compressed to make room for more water thus changing the density of the sub. It would be nearly impossible to store that amount of compressed air or to fill the tank with a high enough air pressure to overcome the water pressure especially at depth.

[@cultofeyes7260]

@@nokaoemauibuilt thanks for the info

[@indykurt]

@@nokaoemauibuilt Thanks, It wasn't answering my curiosity in others comments. They made it sound like they used a compressor using cabin air or tanks that had air in them. The weight of the backup tanks would be great and cabin air is limited.

[@garyvale8347]

why doesn't the compressed air still count as being air on the boat, causing it to float upward ?

[@kuwait5839]

Maybe because the water is still there in the main tank, so they have to get rid of it by using the compressed air

[@PoPMagnus1]

The idea is that if we want to sink, the submarine has to be denser than the water, that is, weigh more pr. volume. We all know that air is lighter than water, but if we compress it, that is decreasing the volume, then we have less volume but the same weight, therefore we have dense air. So we can make air weigh more than water pr. volume by compressing it, allowing us to use it when we need it. When we want to rise up to the surface, we simply increase the volume of the air, by filling it into larger tanks. This way the air gets less dense and we start to rise.

[@aronbeast7]

compressed air is in the form of liquid

[@SaltiDawg2008]

@@aronbeast7 Nope!

[@VitaNova83]

It's not about the weight of the air, that's the same compressed or not, it's the weight of the water you are pushing out of the boat with the air.

[@remybuitenhuis2433]

[@gunprojects5398]

Maybe I’m dumb, but I don’t understand the compressed air part: The compressed air would have to come from inside the submarine in the first place, so it would always have been there, and every time the ballast tanks were filled again, the air would be gone. So where would they get more compressed air to blow out the tank? Like if the compressed air comes from someplace story in the boat, how could it sink in the first place if it had enough compressed air to blow the ballast tanks to rise?

[@DeathOnSernpidal]

I believe when the air is in a compressed state, it's denser and thus even heavier than water.

[@s-w]

He mentioned fumes from fuel engines as one source. I imagine they can also use carbon dioxide waste. So I'm guessing they can't go up anytime they want and may have to wait a bit to get the air they need.

[@formertenant9276]

Relative density is everything

[@VOLightPortal]

What happens if the sub runs out of compressed air? Do you just manually use a water pump to pump out the water?

[@relhage100]

I think if it rises up to the surface, the submarine can refill its compressed air supply. the idea is not to waste all the compressed when the submarine is way below the surface.

[@Hamstray]

​@@relhage100 how is it supposed to refill its compressed air when submerged? i guess the compressed air is for exceptional situations only.

[@Hamstray]

so normal operation diving planes only? that makes much more sense than always having to fill and empty out tanks and compressing air for later use

1:42. i understand the water pressure underneath pushes into the hole but does water also go in through the valve on the top at the same time the air goes out, or does the airpressure push the water away?

[@anouarkrassimovich7481]

the air is coming in from the top, and pushing the water downwards, out of the bottom valve

[@josefvijay6837]

Supper sir ur explanation

[@sai63836]

If there was already enough air to refill the tank when you want to surface why would it sink to begin with? If the air in the tank is light enough to keep the sub from sinking and the compressor is almost equal to the amount of air in the tank wouldnt you need both to be filled with water? Or is water just so much heavier than air just that little amount can weigh it down

[@Zuconja]

I was thinking the same. You are expelling air from one tank with water to dive, but keeping compressed air in another tank to surface. I can''t understand that.

[@voidtheend6686]

bro density is mass/volume. It doesn't depend on amount of gas. When the gas is compressed it has low volume. density-when-filled-with-water= mass-of-submarine+water/volume-of submarine density-without-water= mass-of-submarine/volume-of submarine density is lower in second equation, now do you understand?

[@DeathOnSernpidal]

To put it simply, air when compressed to a small volume is dense and thus heavy.

[@bosshog8844]

the compressed air is expelling the heavy water from the ballast tank.

[@Aketi15]

total air in the submarine is constant right...its getting displaced back and forth, only water can come and go. ?

[@Solveitall813]

Hmmm this still feels like it goes against every physics principle I've ever been told. This is why I sometimes think we're in the matrix

[@relhage100]

most of the time the submarine is neither diving nor surfacing, it is just at equilibrium (depth wise). How is that achieved?

[@lukasdittmer3062]

Water is let into the tank in order to dive. When the desired depth is reached, a specific amount of air is let into the tank so that the average density of the submarine equals the density of water.

[@taiyongkang3966]

but when they try to pump the air into the tank isnt the total airpressure in submarine decrease too? why people inside the submarine dosent explode?

[@lindalakota38]

I already know but where are you getting air. To pump when surfacing ?i asume u have high presurised tanks to rplace the balase.
