Best Answer

At sea level, you have one atmosphere of pressure(14.7 psi). Every 33 ft that you descend adds another atmosphere of pressure. Therefore 3000 ft/33 ft=90.91 ATM. Now add the one atmosphere at the surface to get 91.91 ATM of pressure at 3000 ft depth. Also, 91.91 ATM times 14.7 psi per ATM of pressure equals 1,351 psi.

The air pressure can be determined by doing an equation. This equation is p (air pressure) = 101325 (1- 2.25577 10 to the negative fifth times h (height above sea level) to the power of 5.25588.

It is slightly less than half that at sea level. Atmospheric pressure at 3.1 miles altitude is half that at sea level.

Why can you not breathe 3000 feet off the ground?

This Is Because the atmospheric pressure of earth is always acting.We did not feel this because our blood pressure is equal to atmospheric pressure.It is perfectly possible to breath at this altitude. Mt. Everest, which is much higher than this, has been climbed without any breathing aids.


The temperature at sea level is 20 degrees cecilius the air pressure is 101.3 kpa what is the temperature at the top of a mountain 3000m above sea level?

The temperature at sea level is 20 degrees celsius. What is the temperature at the top of a mountain 3000 m above sea level? Decrease of temperature with height: 6.5 Kelvin per km to about 11 km altitude. That is for a height of 3 km = 3000 m about 6.5 times 3 = 19.5 degrees colder than the ground. So if at ground it is 20°C, at the top of the mountain (3000 m) it will be about 0°C.


What is the values for pressure?

The value for pressure depends on the specific system or situation. For example, atmospheric pressure at sea level is typically around 101.3 kilopascals (kPa) or 14.7 pounds per square inch (psi). However, pressure values can vary greatly in different contexts, such as in a car tire (usually around 30-35 psi) or in a scuba diving tank (around 200-3000 psi).


Why water has a different boiling point at an elevation of 3000 meters than it does at sea level?

Water will boil at approx 100 degrees c at sea level. This is at a pressure of 1 bar.(14.7psi). As you get higher (say mount Everest) there is less pressure thus the boiling point will drop. If you own a car, you will probably know that the radiator in your car is pressurised. This is to enable the water that is used to cool down your car's engine to be able to absorb a lot more heat before it boils (something that shouldn't happen normally!). Due to the water not being allowed to boil, it will continually cool down the engine. Hope that helped!

How many meters above sea level is England?

Large amounts of England, mostly the beaches, are zero metres above sea level. Some bits, like the mountains, are as much as 400m above sea level.


Where are most of the gas molecules in the atmosphere found?

The higher you go above the surface of the earth, the lower the air pressure is, and consequently the less gas molecules your will find within a given volume. Most of the gas molecules in the atmosphere are found below an altitude of 3 kilometers (3000 meters) above sea level.

How are fault block mountain?

Fault Block mountains or Horst- formed when colliding plates build up pressure along parallel cracks (faults) in the Earth's surface. The extreme pressure causes large blocks of land to slip and be uplifted. Elevations are normally greater than 3000 meters above sea level. Example: The Sierra Nevadas of California.
