What is the atmospheric pressure of sea?

1,013.25 millibars
Standard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch, 1,013.25 × 103 dynes per square centimetre, 1,013.25 millibars, one standard atmosphere, or 101.325 kilopascals.

What is the pressure 10m underwater?

2 atm
Examples of ambient pressure in various environments

Environment Typical ambient pressure in standard atmospheres
Pressurized passenger aircraft cabin altitude 8,000 ft (2,400 m) 0.76 atm
Sea level atmospheric pressure 1 atm
Surface of Titan 1.45 atm
10m depth in seawater 2 atm

Is air pressure lower over the ocean?

This is due to an increase in hydrostatic pressure, the force per unit area exerted by a liquid on an object. The deeper you go under the sea, the greater the pressure of the water pushing down on you. For every 33 feet (10.06 meters) you go down, the pressure increases by one atmosphere .

Do oceans have high air pressure?

At the average ocean depth (3,800 meters), pressure on the sea floor is a whopping 380 times greater than it is at the surface. In the deepest trenches, it’s 1,100 times greater! All that pressure causes serious problems for people and other air-breathing animals.

Is 1016 hPa high pressure?

It is generally higher in summer than in winter, with monthly averages varying from a low of 1011 hPa in December and January, to a high of about 1016 in mid summer. It is something of a paradox, however, that extremely high pressure values occur, almost invariably, in wintertime.

What is the water pressure at 33 feet?

29.4 pounds per square inch
This means that at a depth of 33 feet deep in the ocean, there is a total pressure of 29.4 pounds per square inch (psi). This would be 2 ATMs of pressure. One ATM from the water, + one ATM from the water. We call this the ambient pressure or absolute pressure.

What is the water pressure at 20000 feet?

6.4 PSI
Pressure at 100m

Altitude Air Pressure
Sea Level 14.7 PSI
10,000 feet 10.2 PSI
20,000 feet 6.4 PSI
30,000 feet 4.3 PSI

Why can’t we go deep in the ocean?

“The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don’t notice it, the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch. If you went up into space, above the Earth’s atmosphere, the pressure would decrease to zero.

What is the highest pressure in the ocean?

Sometimes pressure is also measured in ‘psi’ (and in the deepest point in the ocean, it is 15,750 psi).

What is the pressure at 2000m below sea level?

Example – Air pressure at Elevation 10000 m

Altitude Above or Below Sea Level Absolute Atmospheric Pressure
feet metre kPa
1500 457 96.0
2000 610 94.2
2500 762 92.5

Is 1019 a high pressure?

The average sea level air pressure is 1013.25 millibars. Notice many of the values in the example image are near this value. Many of the values are between 1014 and 1019 millibars, indicating a general region of high pressure.
