How do you calculate pressure below sea level?
Let us calculate the pressure exerted on the bottom by the weight of the fluid. That pressure is the weight of the fluid mg divided by the area A supporting it (the area of the bottom of the container): P=mgA P = m g A .
When the pressure is half of that at sea level what is the altitude?
3. When the pressure is half of that at sea level, what is the altitude?. Option A. 12,000 ft.
How do you calculate sea water pressure?
Pfluid= Pressure on an object at depth.
- r=rho= Density of the sea water.
- g= The acceleration on of gravity = the gravity of earth.
- h= The height of the fluid above the object or just the depth of the sea.
- Ptotal = Patmosphere + ( r * g * h ).
- Example 1:
- Solution:

What is atmospheric pressure at sea level in KPA?
101.325 kilopascals
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 decrease at 10km compared to sea level?
Atmospheric pressure is around 1,014 millibars (14.7 pounds/inch2) at sea level. At an elevation of 10 km (6 miles or about 30,000 feet), roughly the height of Mt. Everest, pressure drops to 265 millibars. That’s less than 30\% of the pressure at sea level!
Why is atmospheric pressure maximum at sea level?
Most gas molecules in the atmosphere are pulled close to Earth’s surface by gravity, so gas particles are denser near the surface. With greater depth of the atmosphere, more air is pressing down from above. Therefore, air pressure is greatest at sea level and falls with increasing altitude.
What is the pressure of water at sea level?
around 14.7 pounds per square inch
Atmospheric pressure varies slightly depending on the weather and your elevation, but is generally around 14.7 pounds per square inch (psi) at sea level.
What is the atmospheric pressure under water?
14.7 psi
Measurement based on depth of water One atmosphere (101.325 kPa or 14.7 psi) is also the pressure caused by the weight of a column of fresh water of approximately 10.3 m (33.8 ft). Thus, a diver 10.3 m underwater experiences a pressure of about 2 atmospheres (1 atm of air plus 1 atm of water).
