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.
yes for every 5000 feet of elevation your bourdon tube type of gauge will increase by 2 psi. even though the sealed vessel you are checking remains at the same psi. example if i have a sealed tank at sea level and it is reading 12 psi. at 5000 feet the same tank and gauge will now read 14 psi. and at 10000 feet 16 psi. the tank pressure has not changed but the gauge is now out of whack because there is less pressure pressing on the bourdon tube. less atmospheric pressure easier for the gauge to go up.
Yes, unless you are diving to a rather deep depth. One atmosphere is 15 pounds per square inch (or PSI.) A 5 ATM watch should be resistant to water entrainment to a pressure of 15*5, or 75 PSI. That would correspond to a depth of approximately 150 feet, depending on whether you are in fresh or salt water. Watch out, though - many watches not designed for diving have leather or other types of bands that can be damaged by water, especially salt water. (Anything you wear in salt water should be thoroughly rinsed afterwards to get rid of sea salts.)
It is 262 deg Celsius.
15psi
15 PSI represents approximately 34.7 feet of water. This can be calculated using the formula: 1 PSI = 2.31 feet of water.
To calculate head pressure in psi from a head height given in feet you multiply by 0.434. 15 x 0.434 = 6.51 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.
About 2,200 feet.
300 feet of sea water exerts a pressure of approximately 130 psi.
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
To convert psi (pounds per square inch) to feet of water, you can use the conversion factor: 1 psi is equivalent to approximately 2.31 feet of water. This means that if you have a pressure of 1 psi, it would support a column of water approximately 2.31 feet high.
The water pressure at a depth of 300 feet would be approximately 130 psi. This calculation is based on the fact that water pressure increases by 0.433 psi for every foot of depth.
The formula to convert water tank pressure (psi) to feet of head is: Feet = psi * 2.31. This formula is derived from the equation for hydrostatic pressure, which relates pressure to the height of a fluid column.
One pound of water one inch.
There are 46.15 inches of water in a 20 psi pressure. This can be calculated using the formula: 1 psi = 2.307 feet of water, which is approximately 27.69 inches. 20 psi x 27.69 inches/psi = 46.15 inches.
You can lift a locomotive or a house with 1 psi, if the pressure is applied over a large enough area.
