How many meters of pressure can humans currently withstand under the sea

The amount of undersea pressure that humans can withstand varies with different stages and states. Generally speaking, the average person can withstand the pressure of seawater within 10 meters. And some trained professional divers, such as divers carrying oxygen cylinders, are able to withstand more pressure.

Recent studies have shown that some people are able to dive to depths of 330 meters with their equipment, while the maximum depth that humans can currently tolerate is 105 meters when diving with their hands. The invention of the submarine in modern times has allowed humans to reach greater depths, up to **meters**.

It is important to note that as the depth increases, the pressure also multiplies, negatively affecting the diver's body. Therefore, divers need to be cautious and take specific safety measures when doing deep dives.

Without any help, a normal person dives to a depth of about 10 meters, and some professional divers can dive 15 meters, or even 17 meters (which is the limit)!

The depth of the dive is directly proportional to the pressure in the water, and it is ideal to dive to any depth regardless of the pressure in the water.

Because the limit of diving is the limit of man's resistance to water pressure. Secondly, you also need to consider the change in the temperature of the water, because the deeper it is, the colder it gets, and the strength of your breathing.

In short, the depth of the dive is directly proportional to your own physical condition.

There is no official record of the limits of human diving. Judging from the information that can be found, the limit is 330 meters when carrying equipment, and 162 meters and 105 meters when freehand. Whether it's 162 or 105, in short, 100 meters is the limit of human beings, and it belongs to the top masters who occasionally hit the east.

The invention of the submarine in modern times has enabled human activities to reach the deepest reaches of the seabed.

The pressure experienced by a person in the sea at a depth of 100 meters is p= gh= to the 6th power. Frail people can not dive, because they are worried that people's internal organs can not withstand so much pressure, people live under atmospheric pressure that is the 5th power, that is already 10 times larger, to continue to dive is recommended to wear special anti-pressure clothing. The pressure of a person in a 100-meter well is to the 6th power of p= gh= and is less than the pressure in a depth of 100 meters.

It's very big, for example, if we humans are in this place, we're going to die right away.

It is particularly large, and the creatures on land will be instantaneous if they are in this position, and they will not be able to withstand the pressure of the deep sea.

The pressure of 10,000 meters under the sea is very high, because when people get there, their bodies will not be able to bear it.

Liquid pressure: P gh

The density of water is 1g m3, g ?,h=10000m

So ......

One hundred meters is equivalent to about 10 atmospheres.

The density of seawater is about 1030 kg cubic meters.

Liquid pressure calculation formula.

Pressure = Density x Acceleration due to gravity x Depth of liquid.

It can be known that the pressure at a sea depth of 100 m is.

Pressure = = 1009400 nm2

Approximately equal to 100 N per square centimeter.

There is a pressure of 100 N (10 kg) on the area equivalent to the tip of a finger, so the pressure on each person is inconsistent, depending on the body type, you can calculate it yourself, the pressure on the human body is 10 kg per square centimeter.

About 400 meters.

In the case of bare hands, there have been people who have created a depth of more than 400 meters, with the help of ropes and heavy objects to quickly sink, and with the help of air bags to quickly float, but without oxygen, anti-pressure equipment, etc., it can basically be regarded as not using diving equipment.

If you want to dive to a deeper depth, you must use special oxygen, that is, a mixture of oxygen and rare gases, which can dive to a deeper depth, but the danger is further increased, mainly because the blood dissolves other gases.

With the help of a deep-water submarine, on January 23, 1960, Jacques Picard and Don Walsh took a submarine to the bottom of the Mariana Trench in the Pacific Ocean, 10,000 meters below sea level, setting a world record for the deepest human dive in the water.

How much pressure is there on the seabed?

The deepest trench in the world is the Mariana Trench, which is about 11,000 meters deep. Based on the relationship that for every 10 meters of water depth, the pressure increases by 1 atmosphere, and it is not difficult to calculate that the pressure there is about 1100 atmospheres.

The American submersible Trieste once dived to the bottom of the Mariana Trench, and the submersible's shell successfully withstood the test of 1,100 atmospheres, that is, more than 1,000 kilograms of pressure on an area the size of a human fingernail. After careful calculations, Robert Taut believed: there, the submersible withstood a pressure of 150,000 tons, which is equivalent to the weight of two and a half aircraft carriers.

In fact, the steel submersible, with a diameter of 218 centimeters and a wall thickness of 87 millimeters, was compressed by 2 millimeters under the pressure of seawater, causing the paint to peel off the submersible. It is not difficult to imagine that life on land is still possible to survive at such a sea floor. However, on January 23, 1960, when Picard and his son descended to the bottom of the Mariana Trench aboard the Trieste submersible, they spotted a flounder-like fish swimming.

This fish is about 30 centimeters long and 15 centimeters wide, with a flattened body and slightly protruding eyes.

According to the formula p=f s, the deepest part of the seabed is more than 11,000 meters, and 10 is equivalent to 1 atmosphere, so it is 1,100 atmospheres, plus 1 earth atmosphere is 1,101, which is the 8th power of Pa,

One atmosphere is about 10 meters of water, and the deepest part of the ocean floor is 11,000 meters of the Mariana Trench, which is about 1,100 atmospheres.

It can be converted in this way, 1 megapascal per 100 meters, depending on the depth of the sea.

The ocean covers 71% of the Earth's surface. Among them, the deep sea area is an area that is difficult for us humans to reach and study. At the bottom of the Mariana Trench, the deepest part of the ocean, reaches a depth of 10,000 meters, and it is difficult to imagine how much force the sea water has pressed on the front car.

At 10,000 meters of ocean floor, each person's body has to withstand about 101 kilograms of pressure. It can be seen that the pressure of the sea is very terrible, and it takes a lot of courage and perseverance to reach the deep sea and explore the mysteries.

The deep sea is an extreme environment compared to land. There, the water pressure is very high, the temperature is extremely low, the light is very weak, and there are a lot of toxic and harmful substances. In an environment like Huize, there are many wonderful creatures that live.

For example, ancient fossils have documented the evolution of life in the oceans, such as dinosaurs and schools of fish. The discovery of many unknown species in the deep sea by modern scientists also provides us with new perspectives on biological evolution. Therefore, the deep sea is of great significance for scientific exploration and biological research.

With the advancement of human technology, deep-sea probes are now more and more advanced and can withstand very large sea pressures and operate at greater depths. The application of this equipment allows us to better understand the topography and biology of the deep sea, and also helps human beings to better explore and utilize marine resources. We should pay more attention to the protection of marine resources and ecological environment, and cherish this world full of mysteries.
