A submarine is kept at, or close to, surface air pressure.
from the entrance :P +++ Through hatches designed to withstand the pressure of the sea water when submerged.
As a submarine submerges, it is subjected to a high volume of water pressure, which increases the further in depth the submarine goes. They have to be built to be able to withstand this pressure.
It's totally dependent on the hull type, material construction, and overall design, but in general, just before a submarine reaches crush depth is as much sea pressure as it can handle.
Because they need to be able to withstand the pressure of the seawater outside. The deeper a submarine goes - the higher the pressure gets.
An eggshell can withstand a lot more pressure than people think. It can withstand the force of 6.2 pounds or 25 Newtons.
A submarine is made from strong material so it can withstand the tremendous pressure at depths.
because if a submarine goes under water to deep levels, it needs to hold against the air pressure. Yes the person said above.. They have to have a MUCH higher ability to withstand the pressure of the water pushing in against the hull of it.
Through an air and water tight door called a hatch. These hatches are typically thick, round and rounded metal to withstand the sea water pressure at depth.
Yes, water exerts pressure on the hull of the submarine.
When a submarine goes farther down in the water, the water pressure becomes greater. If the submarine goes to far, pipes can explode and let in water, or it can implode the submarine
Yes, the water pressure on a submarine increases as it goes deeper.
The pressure hull of a submarine must withstand the pressure of water at depth. Hundreds of pounds of pressure per square inch translates into many tons of pressure around a pressure hull. If that hull doesn't have the strength to stand up to this, the pressure hull will implode. Steel is a "known quantity" as far as metals. We've used it for a long time, and we have a good handle on its characteristics. Steel alloys are extremely strong, fairly easy to fabricate, and won't double the national debt if we use this metal to make a submarine pressure hull. Steel's weldability and its common availability make it a fine choice for submarine pressure hulls. It's really strong, too. That's a big plus. No one wants to be inside the pressure hull of a submarine when it fails.
