How many pounds of pressure can a submarine withstand?

The maximum that most submarines can dive is about 2,000 feet (2,000/33=60 bars. 60 + 1 bar air pressure is equal to almost 900psi!), so the pressure pushing into the submarine is around 900psi and the air pressure pushing out is only 14psi.

What is the pressure in a submarine?

1 atmosphere
A sub always has a pressure inside that is about equal to the air pressure at sea level (let’s call it “1 atmosphere”). If the outside is also equal to 1 atmosphere there’s no pressure difference and no strain on the shell (hull) of the sub. At 10 meters below the surface, the pressure is 2 atmospheres.

Do submarines have pressure?

Pressure increases by 1 atmosphere every 10 meters. So, yes—that submarine at 300 meters has a pressure on the hull of 31 atmospheres. Because the internal and external forces are not equal (but the surface areas are), there is a much greater force pushing on the outside of the hull than the inside.

What is the pressure inside the submarine?

A nuclear sub maximum operating depth is about 300 meters, so that is about 440 psi. The hull of the sub creates a pressure container, so the outside pressure doesn’t affect the inside pressure. Thus, the interior of a submarine is at normal, surface air pressure.

How is a submarine pressurized?

Now, a submarine is basically a metal container filled with air, and there is just enough air in a submarine to exert the atmospheric pressure at sea level. If the submarine goes underwater, the amount of air within it does not change (unless there is a leak, of course), so the pressure within the sub remains the same.

How do submarines implode?

So in short, implosions are caused by having a greater pressure on the outside of an object than on the inside. But if part of it breaks, the water will rush in, and if it tries to rush in quickly enough, it will make the submarine collapse, or implode.

Can high pressure crush a submarine?

Most submarine hulls are not strong enough to withstand such force, and would be crushed, allowing the outside water pressure to rush in and fill up the low pressure space inside.
