The pressure of liquid acting on a container or other body increases at the rate of 1 atmosphere or about 14.7 lbs. per square inch for every increase of 33 feet in depth. So doing the math results in: 400ft./33ft. = 12.121. Multiplying that by 14.7 lbs. per square inch yields about 178 lbs. per square inch at 400 feet deep.

The pressure at 400 feet below sea level would be approximately 173.5 psi (pounds per square inch). This is because for every 33 feet of depth in seawater, the pressure increases by 1 atm or 14.7 psi.

What is 1500 feet of water converted to psi?

To convert feet of water to psi, use the formula: 1 foot of water = 0.433 psi. Therefore, 1500 feet of water is equal to 650.03 psi.


What is air pressure psi at dead sea level?

The atmospheric pressure at the level of the Dead Sea is approximately 15.47 PSI.


What is the total amount pressure being fed into your engine at sea level if your turbocharger had a boost of 8 psi?

The total pressure at sea level is approximately 14.7 psi (standard atmospheric pressure). With a boost of 8 psi from the turbocharger, the total pressure being fed into the engine would be 22.7 psi (14.7 psi + 8 psi).


What is the absolute pressure at sea level under standard conditions in psi?

Atmospheric pressure at sea level is 14.7 pounds per square inch.Psia(pounds per square inch absolute) is also 14.7 pounds per square inch.However psia starts with zero pounds per square inch at 29.92 in Hg which is a vacuum measurement (absolute vacuum) in inches of mercury or in Hg.14.7 psi atmospheric pressure is as high as atmosphere pressure will ever reach. all measurements below that is a vacuum. That is where psia come in. It can start measurements in a vacuum and continue with the same unit of measurement after it comes out of the vacuum at 14.7 psi.


What is the pressure difference between earth sea level and outer space?

The pressure at sea level on Earth is about 14.7 pounds per square inch (psi), while the pressure in outer space is close to zero psi. This means that there is a pressure difference of 14.7 psi between sea level on Earth and outer space.
