One psi (pounds per square inch) is 27.7 inches of water. An inch of water is a unit of pressure which will raise water one inch. A cubic inch of water weighs 0.0361 pounds, so one psi is one over 0.0361 or 27.7 inches of water.

1000 pounds per square inch (ksi) = 6894.76 kPa, so 1 ton (2000 pounds) per square inch = 13789.52 kPa,and 20 tons per square inch = 275790.4 kPa = 275.7904 MPa[megaPascal].I used ConvertWorld to help with the conversions. See related link.20 tons per square inch = 275.790 megapascals20 tons/in2 = 40000 pounds/in2 (psi)Multiply psi by 0.006894759087 to convert from psi to MPa40000 psi * 0.006894759087 MPa/psi = 275.790 (Googled the conversion rate)
Official FIFA soccer balls must be inflated to 12.5-13.5 pounds per square inch.(PSI).
It depends on flow. 2 PSI for 500 GPM 8 PSI for 1000 GPM 18 PSI for 1500 GPM 32 PSI for 2000 GPM This is per 100' ft If your flows are big, ie. defensive conditions, you must relay for anything over a couple hundred feet in length. Capt. Ridgeway Tumwater Fire
4,000 PSI working pressure
There are 90 pounds per square inch (psi) in 90 pounds.
Pound per Square Inch = PSI means 1pound in terms of pressure will be 1 psi.

To find the maximum flow you would need to know the maximum pressure. A typical fire nozzle pressure would be up to 100 psi with a diameter of 1 to 1.25 inches. The GPM would be between 300 GPM and 460 GPM through the nozzle. If it were simply a 3-inch pipe with an oversized pump, running at 100 psi with no nozzle, you could (in theory) move over 3,000 GPM through the pipe (ignoring friction loss). Even at 80 psi, a master stream through a 2-inch nozzle moves over 1,000 GPM.
The abbreviation for pounds per square inch (psi) is psi.

Friction loss is one of the things we use that's critical when pumping a fire truck with crosslays/hose off the truck. The most common formula runs off 100ft sections in the following size/FL format: 1.75 hose (crosslay/jump line): ~13.5 PSI loss per 100' section 2.5" hose (blitz line): ~18 PSI loss per 100' section 5" hose: .08 PSI loss per 100' section All rates are based on your typical flow rate in GPM's...however the more gallonage the more friction loss. There is an accepted standard for GPM and friction loss: 1.5" hose 100GPM at 30PSI per 100' 1.75" hose 150 GPM at 32 PSI per 100'

Pressure, measured in psi (pounds per square inch), does not have a weight. Pressure is a force distributed over a given area. In this case, 1000 psi indicates the amount of force applied over one square inch.
