How much pressure is 10,000 meters under the sea?

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.

How much pressure is 10,000 meters under the sea? It is said that the hydrostatic pressure of 10,000 meters will reach one ton (1,000 kilograms of square centimeters), which is unbearable for ordinary people, so people must bring equipment to dive when they go in.

At a depth of 10,000 meters, the pressure is equivalent to 1,078 standard atmospheres, which is equivalent to the weight of hundreds of thousands of people, and there is no living thing here.

According to the formula P=Gh, where p stands for pressure, represents the density of water, g stands for gravitational acceleration, and h stands for the depth of water.

The depth of the water is known: 10000 meters.

The density of water is known to be: 1000 kg cubic meters.

The acceleration due to gravity is known to be: meters and seconds.

Substituting a known quantity into the formula, we get:

p = 1000 times times 10000 = 98000000Pa$

So, at a depth of 10,000 meters, the pressure is 98,000,000 Pa.

The Mariana Trench is 10,000 meters deep and has a pressure of up to 100 million Pa at its bottom. Such a high pressure means that even a tank will be crushed to pieces by the powerful water pressure when it comes.

At a depth of 10,000 meters, the hydrostatic pressure will reach 1 ton. In unequipped diving, the deeper the dive, the more the lungs are pressed, and the limit is 100 meters to the left and the right. When there is a respirator, because the pressure of the inhaled gas is very high, which is the same as the pressure of the outside water, the lungs are not compressed and can dive very deep, hundreds of meters, or even deeper.

Because some gases such as nitrogen that will not dissolve in the blood under high pressure will dissolve in the blood and have a bad effect on people, so the gas used for breathing is a special formula, but even so, there is still a limit. It's not because the pressure is unbearable, but because the gas exchange of the lungs changes under high pressure, and at the same time, the deeper the dive, the longer it takes to float, which is also a limitation, because the speed of the rise cannot be too fast.

The maximum pressure on the seafloor is about 1135 atmospheres. The maximum seafloor is estimated to be about equal to = 11,034 atmospheres when the maximum seafloor is 11,034 meters, and the density of salt water is times the density of pure water, so the estimated maximum pressure on the seafloor is about equal to = 11,034 atmospheres.

The characteristics of the internal pressure of the liquid are: the liquid has pressure from the inside in all directions; The pressure increases with depth; At the same depth, the pressure of the liquid is equal in all directions; Liquid pressure is also related to the density of the liquid, and the denser the liquid, the greater the pressure. The amount of pressure inside the liquid can be measured with a piezometer.

For every drop of meters from the water level, the pressure is increased by one atmosphere, and the deepest Mariana Trench is 11,034 meters, and the density of salt water is times the density of pure water, so the maximum pressure on the seafloor is estimated to be about = 11,034 atmospheres.

The Mariana Trench (or Mariana Islands Trench) is the deepest known trench – 10,911 m with a sea density of grams3 p= hg=

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.

The pressure increases with the depth of the sea.

For every 10 meters increase in the depth of the sea, the pressure of the seawater increases by one atmosphere. Of course, this is not an exact value, this is only an approximate value, so in the seawater at a depth of 1000 meters, the pressure of the sea is 100 atmospheres, that is, at this position, the pressure of the seawater per square meter of the object is 1000 tons.

As the depth of the water deepens, so does the pressure generated by the seawater. It is conceivable that if it is in the seawater at a depth of 10,000 meters, the pressure there is as high as nearly 1,000 atmospheric slags, and such a strong pressure is unbearable for the vast majority of living beings on the earth.

The deepest known whale in the world is the Kok's beaked whale, which can dive to a depth of 2,992 meters. In addition, sperm whales can dive to depths of up to 2,200 meters.

The depth of the submarine:

As of July 2023, among the military submarines built by humans, the largest dive depth record is 1,250 meters, which was set by the former Soviet Union's 685 attack nuclear submarine "Komsomolskaya".

Generally speaking, the diving depth of ordinary submarines is between 300-400 meters, the diving depth of nuclear submarines is about 500 meters, and the diving depth of Russian SI and SII-class submarines can reach between 700-800 meters.

It is clear that the submarine is structurally a "hollow" object. It is a hollow body encased in a shell. Therefore, when the submarine is diving, its shell will increase with the depth of the dive, and it will be subjected to more and more pressure.

At the same time, because the inside of the submarine needs to be inhabited, and the environment inhabited by humans generally needs to maintain an atmospheric pressure, it is impossible to increase or decrease at will, so the air pressure in the submarine is relatively stable, and it will not change significantly.
