How a submarine works

The submarine system was designed to be able to run under the surface of the water. For those who are curious about how submarines work.

Submarines can float because of the displacement system that allows water to escape to make room for objects that enter the water

In the laws of physics, if an object enters the water, there will be two pressures that affect it. The two pressures are gravity and buoyancy. An object can float if its density is less than the amount of water it displaces.

Apart from density, submarines can also control their buoyancy using special equipment. Submarines have special tanks that can be changed between water and air.

When it is below the surface the tank will fill with water, while when it floats the tank will be filled with air. Air functions to make the submarine less dense than the water around the ship. Conversely, when it is below the surface, submarines need density so that the tank must be filled with water.

In addition to the vehicle system, to keep the ship's crew underwater, submarines also have special tools to regulate temperature and clean water supplies. Submarines are equipped with pressure tanks that can release oxygen from the ship.

Submarines are equipped with computers to monitor air requirements. Special devices called scubbers and dehumidifiers are also provided to remove carbon dioxide as well as absorb moisture.

There are also submarines equipped with technology to separate salt from seawater so that the water can be used for drinking, cooking and bathing.
