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.
Simply increase the height of the tank as the pressure is a constant (.434) times the height, or approximately 1/2 PSI per foot.
By elevating it higher as every foot higher will increase the static pressure almost a half a pound
Any kind of pain will usually increase blood pressure (temporarily). This is normal.
For every vertical foot of pipe, take that and multiply it by .434.This equation will get within 1/2 -1/4 psi.
A foot of water has a cubic mass of 62.4 pounds per foot
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.
I am 14 and my vertical is 43 inches and i am 4 foot 10. I can dunk on a 10 foot hoop . Last year my vertical was 33 inches but i trained for 3 hours a day to increase it
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.
Water pressure at a depth of about 44 feet is about 20psi
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
The major difference in air pressure and water pressure is the weight. Water is a lot heavier than air. One cubic foot of air weighs 1/12 of a pound. One cubic foot of water weights approximately 64 pounds.
Because of the weight of the water, the water pressure increases at a rate of 2.31 psi per foot of depth.
what is a vetical linear foot
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.)
A pressure foot is used to measure air pressure inside a tank. This means that every square foot of the tank, there is a pound of pressure.
you have decreased the area over which the force is applied, and pressure is force per unit area
I'm not sure what you mean, but if your mean what is the pressure at the bottom of a 100 foot high pipe filled with water, it's 43.3 psi
.433 pounds per square inch per foot of head
Water has about a 4% rate of expansion when frozen. Therefore, one cubic foot of water would increase to about 1.04 cubic feet when frozen.
One foot of water at 4 degrees Celsius is equivalent to 816.2 feet of air at 15 degrees C.
Every one feet the pressure raises by 24.9 psi.
There are 3 pressure points in your foot.
