What is the pressure at a depth of 100 meters?

980000pa。

The analysis is as follows: The calculation is as follows:

1 atm =

p=gh( is the density of the liquid, in kilograms of cubic meters, g = newtons of kilograms, h height, in meters).

The pressure of 1 meter of water depth = 1000, and the pressure of 100 meters of water depth = 9800PA * 100 = 980000PA.

9800 101300 = standard atmosphere).

Solution p=p liquid gh=1000kg m3 (kilogram cubic meter) multiplied by multiplied by 100m=980000pa

A: When the water depth is 100 meters, the pressure is 980000pa.

Here p denotes the pressure of the water, and in addition the capitalization p can denote the power.

Dizzy.. p is the pressure.

Pressure p= gh

where denotes the density of the liquid.

g Needless to say.

h represents the height from the research point to the liquid level (note that it is the height from the liquid level) This is the formula for calculating the liquid pressure, so bring it in and calculate.

p is for pressure, which is density.

According to the pressure calculation formula p=f s can be pushed, p=f s=g s=mg s= vg s= shg s,, about s is.

p= means per cubic meter.

980000pa.

The calculation of going upstairs is fine, but what if you want to consider atmospheric pressure?

If p represents a physical quantity, it can be pressure, power.

980000pa。

The analysis is as follows: The calculation is as follows:

1 atm =

p=gh( is the density of the liquid, in kilograms of cubic meters, g = newtons of kilograms, h height, in meters).

The pressure of 1 meter of water depth = 1000, and the pressure of 100 meters of water depth = 9800PA * 100 = 980000PA.

9800 101300 = standard atmosphere).

Underwater high pressure is generated by the weight of the water above it, just as the pressure of a barometer on land is generated by the weight of air. In diving, underwater pressure is usually expressed in units of depth (meters) or absolute atmospheric pressure. Absolute atmospheric pressure is equal to the weight of water (one atmosphere per 10 meters) plus the atmospheric pressure of the ground (1 atmosphere).

Thus, when a diver reaches a depth of 10 meters in the sea, he is subjected to a total of 2 absolute atmospheres or twice the atmospheric pressure on the ground. For every 10 meters of depth, 1 atmosphere of pressure increases. Therefore, a water depth of 200 meters should be 21 atmospheres.

1 standard atmosphere = Pascal. Do your own tricks.

200 meters underwater is equal to 20 megapascal underwater pressure is also equal to 200 kg of air pressure-Ganzhou Shengfu Motor**** has been focusing on underwater seawater stepper motors, waterproof DC servo motors, underwater waterproof AC servo motors, high-power brushless DC motors, AC permanent magnet synchronous motors, brushless DC motors, hybrid stepper progression, DC servo motors, AC servo motors, AC permanent magnet synchronous servo motors, waterproof IP68 electric drum series products, Manufacturer integrating R&D, sales and service of precision planetary reducer.

The pressure of 1 meter deep water is: 9800 pascals.

Pressure p= gh( density, = 1000 kg cubic meters, g gravitational acceleration, g = Newton kg, h water depth, in meters).

Pressure in water at a depth of 1 meter = 1000 pascals.

1 standard guess the pressure of the air lift = Pascal = the pressure of the meter water column.

Summary. OK.

If you stay in 100 meters of water without any protection, the water pressure can oppress you if you can breathe freely. Therefore, many divers dive into the water wearing unique diving clothing, they can dive to relatively deep positions, but it is dangerous without protection, knowing that the pressure can reach 980000p at a depth of 100 meters.

Nitrogen is insoluble in the blood under the general pressure of the atmosphere, and it is dissolved in the blood when the pressure reaches 3 atmospheres of nitrogen, and the stronger the pressure, the more dissolved in the blood in the water position of 100 meters, a large amount of nitrogen may be dissolved in the blood, but the oxygen that people need is relatively insufficient.

Can 100 meters of deep water pressure crush people?

OK. If you stay in 100 meters of water without any protection, the water pressure can oppress you if you can breathe freely. As a result, many divers wear unique diving suits to dive into the water, they can dive to relatively deep depths, but it is dangerous to be unprotected, knowing that the pressure can reach 980,000p at a depth of 100 meters.

Nitrogen is insoluble in the blood under the general pressure of the atmosphere, and dissolves in the blood when the pressure reaches 3 atmospheres Nitrogen, the stronger the pressure is dissolved in the blood of Sun Zi's blood in 100 meters of water, a large amount of nitrogen may be dissolved in the blood, but the oxygen needed to calm people is relatively insufficient.

Eventually, nitrogen gas flows out of the blood on its own and becomes clogged in the blood vessels, and eventually there is a possibility that the blood vessels will rupture, and if the important blood vessels of the human body are broken, the person will die directly. In addition, divers who are 100 meters underwater are also dangerous, they must breathe with professional equipment, which requires a lot of training power. If the strength is insufficient, sometimes it is not possible to exhale carbon dioxide completely, carbon dioxide poisoning, blackness and dizziness in front of the eyes, poor breathing, and sometimes oxygen poisoning and so on.

The formula for the derivation of underwater pressure is as follows: p = gh (i.e. density of water * gravitational acceleration * depth of water selling mold), g =, for the convenience of calculation, usually 10n kg is taken for large opening, the density of fresh water is generally taken as 1g cm3 = 1000kg m3, and the pressure in water at a depth of 1 meter is p =

gh = 1000kg m3 * 10n kg * 1m = 1 * 10 4n m2 (the unit is also called pa).

For every ten meters of water depth, one atmosphere of pressure increases. The pressure there is 100 million pascals. Converted, every square centimeter has to withstand the pressure of one meal; The Mariana Trench is the deepest ocean on Earth, with a depth of more than 11 kilometers.

What makes the Mariana Trench terrifying is the pressure of the sea.

We usually live at the very bottom of the Earth's atmosphere, and we are under pressure of 1 atmosphere. One standard atmosphere is equivalent to one square centimeter of pressure and kilograms of pressure on an area. An adult** has a surface area of about 2 square meters, so usually our body is subjected to about 20,000 kilograms, which is 20 tons.

The formula for calculating the pressure of liquid with sunflower is p= gh. The pressure p at a depth of 1 meter below the water surface = the pressure p of the Dapei distribution air. + the pressure p produced by the water, if the local atmospheric pressure p.

760 mm Hg, then the pressure generated by 1 meter of water is about 76 mm Hg, then the pressure at 1 meter depth is 836 mm Hg.
