How does a Submarine dive and resurface in the water? | Skill-Lync

Submarines were built as early as the 17th century. The principle they used to dive underwater and resurface has always been the same. In this video, we talk about the working behind how these submarines rise up and sink inside water.

Still i am not clear that once the air leaves while filling the submarine with water and it sinks then how this air is brought back to empty the water for floating on surface.
And let us know that air is also required for combustion of fuel in engine, breathing, cooking etc. How does the staff in submarine manage this?

wow cool, just enogh and not to much information to understand the topic. thanks

[@shikharsaraswat410]

Insightful

[@prasadjadhav3906]

There's got to be a limit to how many times it can pump the compressed air in the tank right? What if the sub sinks and this pump mechanism fails?

[@plasma574]

Lmao then they r screwed

[@Lucasxd331]

Submarines normally have emergency external ballast tanks that can be filled rapidly.
They are normally used to resurface in an emergency, so they can be used if the pumps in the main ballast tank fails.
There is also a manouver where they point their nose up, put engine thrust to the max and pump air in the emergency tank to shoot themselves up.
Redundant systems are everywhere on these things. They can't risk losing billions of dollars in expensive submarines because they failed a simple task.

You should explain WHY compressed air looses it's power in order to keep the sub afloat!!

[@DeathOnSernpidal]

Because when compressed, it's very dense and heavy.

[@theinspector7882]

@@DeathOnSernpidal is that an explaining answer? 🐒

[@DeathOnSernpidal]

@@theinspector7882 It's just an answer.

good and well understandable video

thanks for the video..
But i want to know how does a submarine maintain its depth... can u please make a video on that...

[@drax1938]

♥️♥️😍😍

[@prarthanaasp4706]

Ok but where does the submarine get air from the water body?

[@ershabby]

It means you were not listening carefully

[@eliotvarda]

@@ershabby no dumb sht, he didnt explain the compressed air system, how many times can it be used under water and its properties, ...

[@tjd2326]

But where do the people go if you fill the submarine completely with water?

[@AbsThePunisher]

lol, u fill a specific chamber with water, not the whole submarine :)

[@eliotvarda]

they go to hell

[@itquankazi]

but how does it get the air when it want to resurface

[@somerandompersonhi2028]

It brings the compressed air on board before diving.

[@markyichen6195]

Submarines have compressed air tanks inside them as well..

Jesus loves you.
don't ever forget that.
