History of submarines. 53 sailors destroyed in Indonesia
The Navy submarine, which went missing a few days ago, was found under the sea in three pieces, officials said. All 53 of the crew aboard the submarine have died. We all mourn for the departed
Submarines:
Many people have questions in their minds about how a submarine moves and how it floats in water and then goes under water again.
I will know the history of submarines:
The submarine is based primarily on the "ballast tank theory" of the ancient Greek scientist Archimedes.Ballast tank theory is that if an insoluble object is immersed in water, it will remove water equal to its own volume.
Simply put, if the thing submerged in water is lighter than the mass of water removed, it may float away. If an empty plastic bottle is filled with air, the bottle will remain floating in the water. If the bottle is refilled with fresh water, all the air will be expelled and the bottle will become heavy and sink in the water.Again, if half the air is kept in the bottle, the submarine is operated using the same formula that the bottle will remain floating in the semi-submerged state.
Following the same formula, the submarine has some ballast tankers inside which water and air are pumped with the help of instruments. When the submarine needs to be submerged, water is pumped into these ballast tankers so that the submarine becomes heavy and sinks.
When it needs to be floated again, the water from the ballast tanker is taken out and the air is blown fast with the help of the device so that the submarine floats on the water. However, this does not change the pressure inside the submarine because it uses high quality steel, titanium and other metals. Due to these metals, not only the inside of the submarine but also the outside has the ability to withstand the extreme pressure of water. Oxygen is created with the help of instruments to supply oxygen inside the submarine.
How far can a submarine go under water?
If the submarine has a specified range below that range, the submarine will crash. U.S. nuclear submarines and Russian submarines, capable of carrying the most pressure among current modern submarines, cannot go below 4500 feet. If it goes, the submarine will flatten under the huge pressure of water.
How long can a submarine stay under water?
How long a submarine can stay underwater depends on how much fuel it has and how much food the submarine crew has in reserve. If the diesel is a submarine, the diesel never has to come up after a while. And if it's a nuclear submarine, it can stay underwater for 25 years or more without fuel, but it has to come to the surface for food.
Because the nuclear submarine itself can stay underwater for 25 years or more, but for the people inside it must come up after 6 months. Submarines cannot store food for more than 6 months.
