Is a grenade more deadly in water?

Underwater explosion is no more different in concept of detonation than the explosion in the air, but the effects of this kind of explosion are. It is well known that underwater explosion cause more damage than the same amount of explosive detonated in the air [1].

Do Bombs explode when they hit water?

Explosive detonations which occur underwater create shock waves in a similar manner to explosions in air. Due to the elastic properties of water, the shock wave tends to be of shorter duration, but with a proportionally larger peak overpressure.

What happens if a nuke goes off underwater?

Unless it breaks the water surface while still a hot gas bubble, an underwater nuclear explosion leaves no trace at the surface but hot, radioactive water rising from below. During such an explosion, the hot gas bubble quickly collapses because: The water pressure is enormous below 2,000 feet (610 m).

How can shock wave kill you?

The shock wave following a such a blast can be deadly. The explosion produces an area of high pressure that travels faster than the speed of sound, shattering glass and injuring people.

Do you die instantly in an explosion?

Anyone at or near the center of a nuclear explosion would be killed immediately by the fireball, searing radiation or the blast wave. Otherwise, what you should do depends on how far away you are from the explosion.

How dangerous is a shockwave?

A shock wave can be destructive because it vibrates the material around the point in an extremely hard and fast wave, which causes other things that the material touches to vibrate too, and even make them explode. Shock waves make bombs more dangerous and sometimes are the most dangerous part of an explosion.

How much pressure can humans survive?

A pressure of 6.3 kPa—the Armstrong limit—is about 1/16 of the standard sea-level atmospheric pressure of 101.3 kilopascals (760 mmHg).

Can air pressure kill you?

Here are a few ways that compressed air can kill or seriously injure a person: Compressed air blown into the skin can obstruct an artery and result in an embolism. Inhaled compressed air can rupture your lungs or esophagus. Compressed air blown into the ear can rupture eardrums and cause brain damage.

How deep can a human dive before dying?

In technical diving, a depth below about 60 metres (200 ft) where hypoxic breathing gas becomes necessary to avoid oxygen toxicity may be considered a deep dive.

What is the longest free dive time?

214m

What is the deepest someone has free dived?

Herbert Nitsch

What animals can dive the deepest?

Cuvier’s beaked whales off Cape Hatteras dive farther and stay underwater longer than any other marine mammal.

What’s the highest dive ever recorded?

1. The highest dive. On August 4, 2015 the Swiss diver of Brazilian descent, Lazaro “Laso” Schaller set the world record for diving from the platform, diving from 58.8m (higher than the Tower of Pisa, which measures “only” 56.71 m) and exceeding a speed of 120 km/h at his entry into the water.

Can whales collapse their lungs?

At 1000m down, a Cuvier’s beaked whale experiences 100 times the pressure that they do at the surface, enough to completely compress the air in their lungs. To avoid this, Randall says, they have rib cages that can fold down, collapsing their lungs and reducing air pockets.

What animal can stay underwater the longest?

sea turtles

What animal can hold its breath for 40 minutes?

Sloths

How do whales sleep without drowning?

So how can they sleep and not drown? Observations of bottlenose dolphins in aquariums and zoos, and of whales and dolphins in the wild, show two basic methods of sleeping: they either rest quietly in the water, vertically or horizontally, or sleep while swimming slowly next to another animal.

Do seals sleep underwater?

Seals sleep in the water as well as on land. Because they are sleeping and not actively swimming, they can stay under water much longer than when hunting for food. There are known incidents where seals stay under water up to half an hour, however on the average, their stay is not longer than fifteen minutes.
