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
This video delivers the most information about the subject. Get a better mic, speak louder, and play some light background music and you’ll have a great channel!
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. 👍🏼👍🏼
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.
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
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.
@@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.
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?
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.
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.
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?
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.
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... 🤔
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
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.
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?
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.
sorry, I still dont get it: I would like to dive, ok, I fill my tank with water, weight will increase and all is fine- now I would like to go back to surface, you say I pump "compressed air" into the tank to chase the water out, right? unfortunately, it will not work like that- air, compressed or not will never drive the water out, unless container is airtight (not the same as watertight) and under condition that pressure in the tank is higher than pressure surrounding the submarine at 100m of depth- lets say, 1000 atm? plus, you will need more and more air in wolume to pump in? only solution is to pump the water out of the tank, now you need to air to flow in without pumping it in order for pump the work, isnt it? that cannot be compressed air, so you need another tank to unpack the compressed air to, but what to do with air that was in the tank already, shall we compress that one in the containers we have just emptied? its so confusing- nice diagram though...
Where do you get the air from to refill the main tank once it's been filled with water? Does compressed air loose it's power to keep afloat the sub? THAT'S THE KIND OF EXPLANATION NEEDED TO UNDERSTAND THE MECHANISM. 👎
Bubbles in front of diamond wheel tire Cars make car toward more Swift.Electric magnetic fields HARA in Japanese Wheel Tires front. left Car up.benefit front wheel tires be a density of gas ,bubbles ,and air . below that salt water.

At least he still has a voice. My much more uglier stubborn monotone nasally voice doesn’t agree to work with me as energetic as loud and clear I try to be.
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
Finally a video that explained the compressed air aspect. None of the other videos I watched explained that!
yes!
yeah because explaining to us is a alien
i agreee
even tho his voice is a bit creeping..but the explanation is straightforward...love it
"I think you'll find this video to be... very educational, Mr. Bond."
😅🤣🤣🤣
OMG! so freaking true. he sounds like a bond villian.
😆👍🏻🤣
kind of a annoying voice
Hahahaha
You sounds like you are crying
may be his girlfriend left him but he had to make this video.
@@imdad1 lmao no he is german
Bruh what you saying
@@evovankov he is german he cant talk english right

You just talked about his crying voice
Sounds like some German man sitting in a basement somewhere in his underpants.
Your animation is perfect but your voice is not clear. Why r u crying????
Becaouse his channel no one to subcribe
nice that you explained the compressed air part

Thank youuu I needed a visual of this. Simple and effective 👍
Thank you man , keep it up and ignore the idiots .
This was great, thank you.

😄....I dont care about the voice, he is sharing an amazing knowledge! His voice is unique by the way!😍
Thank you. A very nice simple video. Great for younger children.
I was literally thinking about this while I was learning physics
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?
the air is coming in from the top, and pushing the water downwards, out of the bottom valve
Who cares about the voice as long as he shares his knowledge with us?
thanks it helped alot!
why doesn't the compressed air still count as being air on the boat, causing it to float upward ?
Maybe because the water is still there in the main tank, so they have to get rid of it by using the compressed air
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.

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.
compressed air is in the form of liquid
@@aronbeast7 Nope!
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.
What happens if the sub runs out of compressed air? Do you just manually use a water pump to pump out the water?
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.
@@relhage100 how is it supposed to refill its compressed air when submerged? i guess the compressed air is for exceptional situations only.
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.

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

Great video!

Thank you this was helpful

What kind of aero plane ?
Thank you!

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?
To put it simply, air when compressed to a small volume is dense and thus heavy.
the compressed air is expelling the heavy water from the ballast tank.
Nice animation keep it up more videos
Compressed air part is so important
I can I use your video as presentation on my video
total air in the submarine is constant right...its getting displaced back and forth, only water can come and go. ?
Excellent.
i love listening to your voice!!
I already know but where are you getting air. To pump when surfacing ?i asume u have high presurised tanks to rplace the balase.
can you put ad in the middle of video i have to close and open video 2 or 3 time bcoz of stupid youtube error ad
U educate me thanks a lot
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?
This explanation was super clear and easy to follow
fuck that dislike bar its misleading
Naughty boi
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
How do this type of technology move from one country to another like US to Russia or in reverse
Ok , now if the submarine is submerged deep down then how does it get air to fill the tank ?
Sounds like someone is pointing a gun at you forcing you to speak
FR
Relative density is everything
Thank you
I didn't think this topic would be so creepy and awkward.
most of the time the submarine is neither diving nor surfacing, it is just at equilibrium (depth wise). How is that achieved?
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.
Sounds like a member of Das Boot 😄
Thanks
Thank you so much,As for my college project i was trying to make mini submarine
Supper sir ur explanation
nice way to explain
where is 2nd vid.
thanks
thx
I watched this in class and everyone wondered why u sounded like that 💀
Your voice is fine, no matter what they say, but damn bro, you gotta fill in that negative space.
This debunks gravity. Think about it.
Why is the compressed air precious resource? Can't I simply instead of blowing the air out just compress it in to tank bottles again?
why use compressed air instead of absorbing air from water ?
Im here to learn, but why am i crying?
Good
We're you sick or what??.
Soooo..... Why the submarines have that shape?? It could be just like a boat??
Seams like alot of air to pull down

The air is compressed. That's how it works. Ur welcome
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
Bro forget submerine... Plz dont cry.. we dont wanna know the logic behind
Please never ever eat a half boil egg before recording
Why are you crying bro... Can i help you
