One square foot
Each foot of elevation change is equal to 0.433 PSI of water pressure. Elevating the water tank 10 feet would add 4.43 psi.
Because of the weight of the water, the water pressure increases at a rate of 2.31 psi per foot of depth.
The pressure of water increases about 0.445 psi per foot of depth. If we "zero" our meter so we have "no" pressure at the surface (ignoring the normal 14.7 psi of air pressure at sea level), at 18 feet we will have 0.445 psi/ft times 18 feet, which is 8.01 psi, or right at about 8 psi.
There can be aby number of psi in a cubic foot because psi is a measurement of pressure and the gas can be any pressure you care to make it.
7000 PSI
Each foot of elevation change is equal to 0.433 PSI of water pressure. Elevating the water tank 10 feet would add 4.43 psi.
Depends on the height. You gain approximately 0.4 psi for every foot of elevation; so at 10 foot elevation you will have ~4 psi.
Fill up a 5 gal bucket of water at full pressure and time it.
10 feet x 0.433 psi/ft = 4.33 psi at the base of the cylinder.
90 PSI is a bit high....you can check water flow (gallons per minute) by filling up a 5 gal bucket at full open and time it.
One foot of water at 62 degrees F = 0.433 PSI. To find the PSI for any feet head not listed, multiply the feet head by0.433.the answer would be 25.99 PSI in water at 62 Degrees Fahrenheit
0.43197 psi
Water pressure at a depth of about 44 feet is about 20psi
If it is fresh water, and the surface is at sea level, then the pressure at the surface is 14.69 psi. As you submerge, then the pressure from the weight of the water above you is added to the air pressure above the water. For each foot that you descend, the water pressure will increase by 0.4331 psi, so at 328 feet deep, the water pressure is 142.0568 psi. Add the 14.69 psi air pressure to get 156.7468 psi.
The lower the depth, the more psi. It falls back to the base weight of the liquid. For example a foot of water is equal to .433 psi. Every additional foot of depth is another .433 psi of downward force.
Because of the weight of the water, the water pressure increases at a rate of 2.31 psi per foot of depth.
about 2 psi. (0.5 psi / foot of depth)
