The pressure increase is dependent on density of the water. Pure water at 60F has about 27.78 inches of water column (INWC or INWG) per psi or approximately 0.43197 psi/ft. This is from memory; but it should be close.
Fresh water: 0.43 psi per foot Sea water: 0.44 psi per foot.
So, for each additional 10 feet of depth, figure about 4.3 to 4.4 psi increase in pressure.
You can calculate this yourself by using the fact that fresh water weighs about 62.4 pounds per cubic foot (pcf) and sea water weighs about 64 pcf. Divide those numbers by 144 (the "footprint" of one cubic foot, 12 x 12) and there you go.
It's interesting to note that this pressure is independent of volume or expanse. i.e. the water pressure behind a fresh water dam at 100 feet deep is about 43.3 psi regardless of whether the dam's reservoir is 25 miles long or 10 feet long. Depth and density are the only relevant parameters needed to determine pressure.
Dive pressure, however, would be the water pressure of 43.3 plus the air pressure above the water. So the net pressure on your ears & body would be 43.3 plus 14.7 (one atmosphere)totalling 58 psi,or about 4 atmosphers. That's four times our normal experience. Worthy of careful consideration.
Regarding diving - internal pressure inside ones body EQUALS the atmospheric pressure (14.7 psi). [Otherwise we would be squashed by the athmospere.]
Therefore, the net result is still dependent on depth ONLY - in example given it would be around 2.95 atmospheres.

How can I use a cold water storage tank to increase my water pressure?
By elevating it higher as every foot higher will increase the static pressure almost a half a pound
How much pressure does a 10-foot vertical pipe filled with water put on the cemented joints of a newly laid sewer line?
Every foot of water (i.e. foot of head) equals 2.31 psi (i.e. pounds per square inch).answerI think that first answer is backwards. It takes 2.31 vertical feet of pipe to create 1# of pressure. Stated another way, one foot vertical equals roughly .434 psi. When a plumber tests the underground with a ten-foot stack, approximately 5 pounds pressure is applied. That is why some codes allow a 5 pound air test in lieu of water in cold weather and in other situations where it is more practical.
How do you calcuate water pressure in a pipe?
For every vertical foot of pipe, take that and multiply it by .434.This equation will get within 1/2 -1/4 psi.
Can foot pain increase blood pressure?
Any kind of pain will usually increase blood pressure (temporarily). This is normal.
How much pressure is in 328 feet of water?
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.
How can you increase water pressure from a well?
Simply increase the height of the tank as the pressure is a constant (.434) times the height, or approximately 1/2 PSI per foot.
If a pressure reading is 20 psi what is the pressure in foot of water?
Water pressure at a depth of about 44 feet is about 20psi
How many Pa does it take to move water one vertical foot?
2985.43 pa
Why do you stand in 1 foot you increase your pressure?
It's actually to do with surface area. One foot decreases your area, therefore all your weight (pressure) is on one foot. 2 feet would distribute the weight
Why is water pressure higher in deeper water?
Because of the weight of the water, the water pressure increases at a rate of 2.31 psi per foot of depth.
What would water pressure be from a 5500 gallon cistern 100 feet high?
The water pressure depends ONLY on the height, and the density of the liquid - not on the number of gallons. You basically calculate the weight of a vertical column of that height, and divide by the base area. The column can be of any cross section - for example a square centimeter, a square meter, or a square foot. (For water, the pressure is about 1 bar for every 10 meters.)
