Every 10 metres of water adds 1 ATM, so a depth of 10 metres is 2 ATM (the atmosphere of pressure at the surface plus the pressure of 10 metres of water). 10 ATM is reached at 90 metres, or approximately 295 feet (10 metres is approximately 33 feet).
(The 1atm/10m is true for salt water at 15C; actual pressure/depth depends on water - fresh Vs salt - and temperature, but 1atm/10m is a good guideline for most purposes.)

Is 2 ATM the water pressure at 20 meters?
Yes, 2 ATM is equivalent to the water pressure at a depth of approximately 20 meters underwater. This is because each additional 10 meters of depth adds around 1 ATM of pressure.
What is the absolute pressure at 10m sea water depth?
The absolute pressure at a depth of 10 meters in sea water can be calculated by adding the atmospheric pressure to the pressure due to the water column. At 10m depth, the pressure due to the water column is approximately 1 atm (equal to 10 meters of water column) and adding the atmospheric pressure of about 1 atm gives a total absolute pressure of around 2 atm.
How deep would you need to dive to experience a pressure of 2 ATM What would be the pressure at a depth of 100 m?
To experience a pressure of 2 ATM, you would need to dive to a depth of 20 meters (2 ATM = 1 ATM (surface) + 1 ATM (pressure at 10 meters depth)). At a depth of 100 meters, the pressure would be approximately 11 ATM (1 ATM at surface + 1 ATM for every 10 meters).
What does the abbreviation ATM on a waterproof watch stand for?
ATM is the depth by which water resistance is measured on a watch. ATM stands for Atmospheres. 1 atmosphere is equivalent to appx. 33 feet depth in water. So if a watch is 3 ATM = 100 ft. water resistant.
What does 10 ATM mean on a wrist watch?
It means 10 atmospheres. This usually indicates a watch will remain waterproof to a depth of 10 atmospheres or about 340 feet of water.
State how the pressure in liquid depens on the depth of the liquid?
Density of liquid (kg/m3) * gravitational constant (m/s2) * depth (m) = (extra) pressure under liquid (Pa) Density of water = 998 (kg/m3) gravitational constant = 9.81 (m/s2) 1,000 ATM = 1.013*10-5 Pa Raw formula: pressure under water = 1 (ATM) per 10 (m) depth
What is the meaning of ATM on a wristwatch?
"ATM" stands for "atmospheres," and the ATM rating on your wristwatch is the depth before the sea surface at which you can safely wear your watch. Most watches are rated between 1 ATM and 10 ATM. For more information, see the Related Link.
According to the phase diagram for H2O what happens to the phases of water at 0 degC as the pressure is increased from 0 ATM to 10 ATM?
water changes from a gas to a solid to a liquid
What does 3 ATM mean on a wrist watch?
The term "atm" means "atmosphere" It's a term used to measure pressure. One atmosphere is the atmospheric air pressure at sea level. On a watch it is a measure of water resistance. Under water the pressure increases by one atmosphere for every 10 metres of depth. So "10 atm" on a watch means it is water resistant to 100 metres. "30 atm" is water resistant to 300 metres. http://en.wikipedia.org/wiki/Atmospheric_pressure
How deep is 100 ATM?
One atmosphere of pressure is equal to the pressure at sea level. Therefore, 100 atmospheres would be roughly equivalent to the pressure experienced at a depth of about 3,000 feet (914 meters) underwater.
What is the absolute pressure at the bottom of a lake that is 25 m deep?
The absolute pressure at the bottom of a lake is the sum of the atmospheric pressure and the pressure due to the water column. At a depth of 25m, the pressure due to the water column is (density of water) x (acceleration due to gravity) x (depth) = 9800 Pa. Adding the atmospheric pressure of about 101325 Pa, the absolute pressure at the bottom of the lake is approximately 111125 Pa.
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).
