As submarines go deeper they are surrounded by more and more pressure from the water arround them. There are not currently any submarines that can withstand that amount of water pressure.
No, hurricanes do not affect submarines operating below the surface. Sea conditions do not affect submarine operations because, in general, they run deep enough to avoid the swell on and near the surface.
They caused anxiety and sink ships.
To withstand the external pressure.
if it aint regulated you would suffercate
To protect the occupants from extreme pressure.
Submarines cannot reach the deepest parts of water because of the pressure or water and deepest surface is not a smooth, its full of rocks and sea plants.
To withstand high water pressure when they are submerged at sea.
Pressure can affect the solubility but the effect is not important.
They were used in the first world war in submarines. The are used now also for submarines and also war tanks. The outer coating of the periscope for the submarines were firm and waterproof for protection from the water pressure. As for the war tank the periscope is able to turn 360 degrees.
because they have to withstand the pressure of the water when they go down under water. and to keep the people safe :)
Submarines don't have windows, at least not any that are used for viewing outside of the hull while submerged. They are used in some submarines as bridge viewing windows, but they're subjected to ambient sea pressure when the boat submerges, not direct sea pressure like the hull is.
