What is the average air pressure in a hole 500 meters below sea level?

Answer 1

795.0

Answer 2

The standard atmosphere (symbol: atm) is a unit of pressure and is defined as being precisely equal to 101.325 kPa Air Density decreases at a rate of 2.9% - 3.0% for each 1000 ft. of elevation above Sea Level. See Standard Atmosphere below for background information. 1 000 feet = 304.8 meters So in rough terms You will lose about 1% of the pressure for each 100 meters due to elevation increase 0m = 101.325 or 1 atm 100m =101.32500 - (101.32500 * .01) = 100.31175 200m = 101.32500 - (101.32500 * .02) = 99.2985 -------------------------------------------------------------------------------------------- The above was taken from an answer to a related question on this site. If the reverse is true, the you simply add 1% of pressure for each 100 meters below sea level; thus the air pressure 500 meters below sea level, could be 106.39125 or 1.05 atm?

Answer 3

The average pressure at sea level is 14.7 pounds per square inch, or 1013.25 millibars.

As you move to elevations below sea level, the pressure increases at the same rate as the decrease observed above sea level: the pressure increases by about 12 millibars (0.17 psi) for every 100 meters of descent. The lowest non-subterranean point on Earth, the shore of the Dead Sea, is 430 meters below sea level, and has an atmospheric pressure about 5% higher than is found at sea level (in the range 1055-1065 mb).

* Underwater, the pressure increase is much greater because it is water, not air, that is being pushed down by the weight of the water above it. The increase is about 1 additional atmosphere for every 33 feet below the surface.

* In caves, the increase in ground temperature (varies from 10 to 50 degrees C per km) can reduce this increase, but it can still be higher where the air is artificially cooled.
