- How does the submarine sink and float - Submarines are ingenious pieces of engineering designed to transport humans securely through this dangerous environment. They are also meant to be unseen, undetected, invisible, silent force that could or could not be anywhere at any time. With these unique capabilities, these naval vessels are capable of propelling itself beneath the water as well as on the water’s surface.
Interestingly, have you ever wondered how does the submarine dive and resurface according to Archimedes principle? In today’s episode, we will explain this topic in detail, and you will find the answer only at this channel!

Good video. Can anyone tell please how does submarine control it's stability so that it doesn't tip off on the sides?
We are so sorry for that we got any mistake in writing
Submarines have ballast tanks as described which are used to balance the front to back and change depth and then they also have smaller tanks on the sides called trim tanks which use the same concept to balance the ship from side to side
Weighted on the bottom.
The trim tanks are at the bottom below the lowest deck and ballast tanks are further fed and aft than the picture depicts
Submarines did NOT carry nuclear warheads in ww2. This wasn’t seen until the Cold War.
Thought. I was the only one who heard this and laughed 😂😂
and where does the pressurized air come from, to make the submarine float, when the submarine is under water?
There is oxygen in water as if there is no oxygen then there won’t b any fish
How exactly is the sea water expelled from the ballast tanks? You really need to include such information.
I think, but I don't know, the air can also be pressurised again (opposite of 3:35). It could be expelled and 'refilled and repressurised' once at the surface, but letting it all go (3:25) will also giveaway where the submarine is.
@@studio48nl you are correct, high pressure air is pushed into the tank with the top vents closed which forces the water to go back into the sea thru the bottom of the ballast tank. The air pressure required for doing such depends on the depth of the submarine and the sea pressure around it.
Low pressure blower or high pressure air

Love from Thailand lndia and Malaysia.
very informative i learned a lot
Up and down
Another unsatisfying dive/surface video. I want to know HOW the air is stored so the vessel can surface after being submerged. Every video I have watched glosses over this important step!
We have air banks that we fill with an air compressor, they are pretty much always full. But we normally use low pressure air once we reach the surface cuz it gets the job done. High pressure is for emergencies
It doesn't need any air. It simply drives to the surface using the dive planes. Kind of like how a plane flies higher. There are tanks of compressed air already on board to use in case of an emergency.
where they get the air . surely they cant suck the air in the sub itself it will causes crack like in the bottle
It don’t cuz we know how much we need. We get it from the air before goin down
how the fuck did new high pressure air comes in when submarine needs to re-surface. As it is already sorrounded by water deep inside the ocean. 🙇
That's exactly what I'm thinking about. It's very easy to understand how it dives. But very hard to understand how it takes the air in again if its surrounded by water
@@renatomartins2086because surfacing means we open a hatch and we got AIR

I am sure that in the future they are going to do it by turning gas into the liquid and back to gas. Without any water.
What gas are you talking about? Air? That’s a mixture of gases. And if you compress air enough it turns into “liquid air” (still less dense than water). The problem arises due to proportions of volume with gas forms vs liquid forms. Think about a jug holding a gallon of water okay. Imagine that jug is the ballast tank of a sub and that 1 gallon of water is what is needed to increase the density of the submarine enough to make it submerge. If that gallon of water was turned into gaseous form, water vapor, holding it would require a container about 1700 times the volume of the jug that originally held 1 gallon of liquid water. So whatever element you’re imagining could be used when you say converting it back and forth from gas to liquid, its gaseous form (like in the water example) needs a container many, many, many times larger than the container needed to hold the same amount (in terms of mass) in the element’s liquid form. If the math and science geniuses over the years involved in inventing, designing, innovating, and building submarines had found a simpler way than the current method… they’d already be using it.

video doesn’t explain anything, and uses mostly Russian/USSR stock footage which is sickening

Well we have to accept Germans Are genius not Americans Nor Russians they just used German Scientists 😎
