What is the pressure in atmospheres on the body of a diver if he is 21 ft below the surface when the atmospheric pressure at the surface is 0.94 atm?
The pressure of freshwater increases by 1 atm for each 34 ft of depth. The pressure of seawater increases by 1 atm for each 33 ft of depth. If surface pressure is 0.97 atm, simply add that pressure to the pressure of the water.
For seawater, you are exactly 1 atm below the surface... So:
1 atm + 0.97 atm = 1.97 atm
For freshwater, divide 33 by 34 to get the fraction of an atmosphere you're adding to your surface pressure:
33/34 * 1 = 0.97 atm
Then add that number to the surface pressure:
0.97 + 0.97 = 0.94 atm

About What fraction of atmospheric pressure greatest at the surface of earth?
At the surface of the Earth, about 99% of the atmosphere's total mass is located below 32 km. This is where most of the atmospheric pressure is concentrated. Therefore, the greatest fraction of atmospheric pressure is present at the Earth's surface.
What is the pressure at 500 m below the surface?
At a depth of 500 m below the surface, the pressure would be approximately 5 atmospheres (1 atm for every 10 m of depth).
What kind of pressure does a column of air exert on the air or surface below it?
A column of air exerts atmospheric pressure on the air or surface below it. This pressure is caused by the weight of the air above pushing down on the lower air or surface.
How do volcanic eruptions create geysers?
By creating atmospheric pressure below the surface, causing temperature to rise.
When molecules from below the surface of a liquid become a gaswhat is happening?
Boiling - the vapor pressure exceeds atmospheric PLUS the pressure of the depth of the liquid.
What is the expected pressure of air in lungs of a diver at 4 meters below the sea level?
At 4 meters below the sea level, the pressure exerted by the water column above the diver would be approximately 0.4 atmospheres higher than atmospheric pressure at the surface. Therefore, the expected pressure of air in the diver's lungs would be the sum of this increase and atmospheric pressure.
Why does Atmospheric pressure exists because air has what?
Atmospheric pressure exists because air has weight. The weight of the air above exerts a force on the air below it, resulting in pressure at the Earth's surface.
What is negative gauge pressure?
Below atmospheric pressure
How does the atmospheric pressure below sea level compare with atmospheric pressure at sea level?
It is greater.
What is the average psi on the earths crust?
Standard atmospheric pressure at sea level is about 14.7 PSI. So, then what is the pressure at about 5,645 feet below the surface of the earth?
How does the atmospheric pressure at altitudes sea level compare with atmospheric pressure at sea level?
the atmospheric pressure below sea level is highter (novanet)
What is Earth's inferred pressure at a depth of 3500 km below the surface?
At a depth of 3500 km below the surface, Earth's inferred pressure is estimated to be around 1.3 million times higher than atmospheric pressure at the surface. This extreme pressure is due to the weight of the overlying rock and the compression of material at such depths within the Earth.
