# How does pressure work in the ocean?

## How does pressure work in the ocean?

In the ocean, pressure works the same way, but instead of just having a column of air over you, you also have the weight of all the water above you, pressing down on your lungs. And water is much heavier than air. For every 10 meters you go below the surface, the pressure increases by one atmosphere.

## How do animals survive the pressure of the deep ocean?

Unique anatomical structures, proteins, and cell membranes allows them to withstand crushing pressure and darkness. This deep sea creature can withstand more water pressure than 1,600 elephants standing on its head.

## How do organisms live under high pressure?

Generally the deep sea organisms have the same pressure as that of their surrounding water. These organisms also possess large lungs, air sacs which helps in maintaining their internal pressure of the body so as to overcome the external pressure this way the equilibrium is maintained and survival also maintained.

## What is water pressure in the ocean?

If you are at sea level, each square inch of your surface is subjected to a force of 14.6 pounds. The pressure increases about one atmosphere for every 10 meters of water depth. At a depth of 5,000 meters the pressure will be approximately 500 atmospheres or 500 times greater than the pressure at sea level.

## Can a human dive to the Titanic?

No, you cannot scuba dive to the Titanic. The Titanic lies in 12,500 feet of ice cold Atlantic ocean and the maximum depth a human can scuba dive is between 400 to 1000 feet because of water pressure.

100-130 feet

214 meters

## What is the longest time someone has held their breath?

22 minutes and 22 seconds

## How many free divers die each year?

Free diving is dangerous, and in some cases deadly sport. There are about 5,000 free divers around the world, and an estimated 100 die each year.

35,858 feet

## Can you dive in a 6 foot pool?

If you are not installing a diving pool, consider the safe depth of 3 feet (1 metre) in the shallow end to 6 feet (1.8 metres) in the deep end.

## How deep can US submarines go?

A nuclear submarine can dive to a depth of about 300m. This one is larger than the research vessel Atlantis and has a crew of 134. The average depth of the Caribbean Sea is 2,200 meters, or about 1.3 miles. The average depth of the world’s oceans is 3,790 meters, or 12,400 feet, or 2 1⁄3 miles.

## Can you smoke on a submarine?

The Navy announced today a ban on smoking aboard submarines while they are deployed below the surface after medical testing showed non-smokers suffered effects of second-hand smoke. Mark Jones of the Commander Naval Submarine Forces out of Norfolk, Va., said about 40 percent of the submarine sailors are smokers.

## Why do submarines not have windows?

There is no reason to have a window because submarines are submerged almost all the time. Submarines operate in open ocean and stay away from any kind of ocean floor. Using external lights to allow people to look through a window would defeat the purpose of being stealthy.

## How thick is a submarine hull?

Making the hull. 4 Steel plates, approximately 2-3 in (5.1-7.6 cm) thick, are obtained from steel manufacturers. These plates are cut to the proper size with acetylene torches. 5 The cut steel plates are moved between large metal rollers under tons of pressure.

## Can a bullet penetrate a submarine?

The pressure hull of a submarine can be 30 mm or even more, depending on the rated pressure, so no, you are not going through that with a rifle bullet. You might do some damage with an advanced AP bullet, but common bullets will barely scratch the surface.

## How strong is submarine hull?

Prior to the Balao class U.S. submarine, hulls were built of mild steel (MS) which had a maximum tensile strength of 60,000 pounds per square inch and a yield strength of 45,000 psi with 23 percent elongation.

## Are submarines faster than ships?

A submarine can be faster than a boat. Nuclear power allows submarines to go faster than surface ships. (This may be true.) The fastest submarine is claimed to be the Soviet K-162, launched in 1969, with a top speed of 44.7 knots (82.8 km/hr).

## Who has the fastest submarine?

Soviet Red Banner Northern

## Why are subs faster underwater?

A submerged sub offers less resistance when submerged, principally because there is no energy dissipated in generating big waves on the surface, Therefore, if it’s using the same propulsion system submerged as on the surface, it can go faster submertged.

## How fast can subs go underwater?

How Fast Can a Submarine Go? This is classified as well. However, U.S. nuclear-powered submarines can go faster than 23 miles per hour, which is 37 kilometers per hour or 20 knots (nautical miles per hour) underwater.

Virginia class

## Can you escape a sinking submarine?

There are two options available for the crew of a submerged disabled submarine (DISSUB); escape or rescue. Escape is the process where the DISSUB’s crew leaves the boat and reaches the surface without external assistance; while rescue is undertaken by outside parties who remove the trapped crew from the submarine.

## Has anyone died in a submarine?

Kursk explosion The explosion and the flooding by high pressure seawater killed the majority of the submarine’s 118 sailors. Twenty-three survived in the stern of the submarine, but despite an international rescue effort, they died several days later either from a flash fire or suffocation due to a lack of oxygen.

## Could the Kursk crew have been saved?

Most of the crew had died instantly. But 23 men remained alive trapped in a leaking compartment at the back of the sub. They could have been saved, but for days the Russians turned down all offers of help despite the fact their own search and rescue capacity was pathetic.

## Which country has the most advanced submarine?

Here are the 10 countries with the most submarines:

• United States (66)
• Russia (62)
• Iran (34)
• South Korea (22)
• Japan (20)
• India (16)
• Turkey (12)
