How many PSI is a foot of head?
1 PSI
The relationship between PSI and feet of head is that 2.31 feet of head = 1 PSI. Translated, that means that a column of water that’s 1-inch square and 2.31 feet tall will weigh 1 pound. Or, one-foot column of water that’s 1-inch square weighs . 433 pounds.
How do you convert ft lbs to PSI?
Divide the number of pounds per square foot by 144. The quotient is the pounds per square inch. For example, 2,160 pounds per square foot converts to 15 pounds per square inch (2160 psf รท 144 = 15 psi).
How do you calculate head pressure?
Divide the depth in inches by 27.71-inches/psi, or the depth in feet by 2.31-feet/psi which are the English unit conversion factors. The result is the water head pressure expressed in psi.
What is the water pressure at 60 feet?
Depth and hydrostatic pressure.
| Height of Water Column | Pressure | |
|---|---|---|
| (m) | (ft) | (psi) |
| 40 | 131 | 56.9 |
| 50 | 164 | 71.1 |
| 60 | 197 | 85.4 |
What is the psi at 1000 feet underwater?
Each 10 metres (33 feet) of depth puts another atmosphere (1 bar, 14.7 psi, 101 kPa) of pressure on the hull, so at 300 metres (1,000 feet), the hull is withstanding thirty atmospheres (30 bar, 441 psi, 3,000 kPa) of water pressure.
Can you convert PSI to LBS?
PSI is a unit of measure for pressure, and pressure (PSI) is the amount of force (lbf) applied per unit of area (in2). To convert PSI to lbs, simply multiply the pressure by the area over which the force is applied.
Is PSI and lb in2 the same?
The pound per square inch or, more accurately, pound-force per square inch (symbol: lbf/in2; abbreviation: psi) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch.
How do you calculate suction pressure?
The equation for determining how much of a suction lift you can pull with your pump you can take your Atmospheric pressure(Pb) subtract your Pump NPSHR, Vapor Pressure (Vp), friction losses (hf) and NPSH Margin (Safety factor) and you will have your maximum suction lift.
