It would actually take more than four hours to safely surface from a 60-minute dive at a depth of 160 feet..

## What is crush depth for a human?

Human bone crushes at about 11159 kg per square inch. This means we’d have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean.

## Did they use real sharks in 47 meters down?

All the Great Whites seen in the movie were computer generated. However, as any modern movie actor will tell you, they as well as the digital artists need something on the set for eyelines to follow and animated creatures to be properly placed within the frame.

## What is the water pressure at 47 meters?

At 47 meters down, a person is experiencing 5.67 atmospheres, which means they blaze through their air at nearly six times the rate they would at the surface.

## Can the bends be cured?

Prognosis or outlook of people who develop the bends varies with the following factors: Prognosis is good with hyperbaric oxygen treatment. Delay to hyperbaric oxygen treatment: Although reports show that divers can do well after days of symptoms, delay in definitive treatment may cause damage that is irreversible.

## How deep could a ww2 U boat dive?

World War II German U-boats generally had collapse depths in the range of 200 to 280 metres (660 to 920 feet).

## At what depth does the bends occur?

The Bends/DCS in very simple terms Anyone who dives deeper than 10 metres (30ft.) while breathing air from a scuba tank is affecting the balance of gases inside the tissues of their body. The deeper you dive, the greater the effect.

## Who died 47 meters?

47 Meters Down was directed by Johannes Roberts (The Strangers: Prey At Night) and the movie is notable for a surprise twist that reframes the ending. Towards the end of the movie, Lisa finds herself alone in the cage after Kate is seemingly killed by a shark.

## At what depth will the ocean crush you?

Human beings can withstand 3 to 4 atmospheres of pressure, or 43.5 to 58 psi. Water weighs 64 pounds per cubic foot, or one atmosphere per 33 feet of depth, and presses in from all sides. The ocean’s pressure can indeed crush you.

## How deep do navy seals dive?

100-130 feetNavy SEALS commonly don’t need to be in extremely deep water for their work. But with how extensive their training is in diving, they are likely to be certified to dive 100-130 feet or deeper with many technical certifications on top of that.

## Can water pressure crush a human?

The pressure of the water on a deep-diver’s body can crush him. It can easily cause death. Coming up from the extreme pressure of deep water to the much lower pressure at the surface is especially dangerous. Ascending too quickly can cause a fatal condition called “the bends.”

## What happens if you go too deep in the ocean?

As you descend, water pressure increases, and the volume of air in your body decreases. This can cause problems such as sinus pain or a ruptured eardrum. As you ascend, water pressure decreases, and the air in your lungs expands. This can make the air sacs in your lungs rupture and make it hard for you to breathe.

## Why do they call it the bends?

The condition is called the bends because the joint and bone pains can be so severe they double you over. What happens inside your body during decompression sickness is similar to what happens when you open a carbonated drink.

## Why do whales not get the bends?

Under less pressure at shallower depths, the nitrogen bubbles expand in the bloodstream and tissue, causing pain and damage. … This mechanism would protect cetaceans from taking up excessive amounts of nitrogen and thus minimize risk of the bends, says lead author Daniel García-Parraga of the Fundacion Oceanografic.
