How can water be removed from a submarine that is submerged?
If a submarine is opened, while it is submerged, water would get in because of the difference between the pressures.
For example, I have seen that there is a diving room in submarines, these rooms are in direct contact with the sea but the level of the water remains steady.
Can anyone explain for me this phenomenon?
If just the water level was steady, why don't we threw the water directly to the sea?
