Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types. You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. It is the pressure resulting from a force of one pound-force applied to an area of one square inch.Ĭonversion calculator for all types of measurement units. Your value gets instantly converted to all other units. 2: Enter the value you want to convert (foot of water). You can also go to the universal conversion page. To switch the unit simply find the one you want on the page and click it. The pound per square inch or, more accurately, pound-force per square inch (symbol: psi or lbf/in² or lbf/in²) is a unit of pressure or of stress based on avoirdupois units. 1: This is a conversion chart for foot of water (Water (at 39.2F, 4C)). The dynamic pressure as head is typically measured with a pitot tube.You can do the reverse unit conversion fromįoot of head to psi, or enter any two units below: Enter two units to convert From: This calculator can be used to calculate air velocity in a duct or air stream from a measured head of water column. The constant C and temperature: Air Temperature Imperial UnitsĬ = constant (4005 for temperature 70 oF) Note! - these simplified equations must be relaculated for other air temperatures and densities. If the flowing fluid is air with ρ f = 1.205 kg/m 3 (20 oC) and the reference fluid is water with ρ w = 1000 kg/m 3 - (2) can be simplified to The dynamic pressure as head is typically measured with a pitot tube. This calculator can be used to calculate water velocity in a pipe or water stream from a measured head of water column. Still have questions Find more answers Ask your question Continue Learning. One PSI is equal to 2.31 Feet of Water and that means we can also write it as 1 PSI 2.31 Feet of Water, feel free to use our online PSI to Feet of Water. V fpm = velocity (ft/min) Water Flow - Head to Velocity Calculator 2297 Reviews Study now Add your answer: Earn + 20 Q: 1 psi will lift water how many feet Write your answer. Therefore, to find the feet head of water for any pressure. H w (ft H2O) = 0.0155 (v fpm / 60) 2 (3f) How many Meter of water column make 1 Pound per square inch Measurement calculator that can be used to convert psi to mH2O (Pound per square inch to Meter. NOTE: One Pound of pressure per square inch of water equals 2.31 feet of water at 60 Fahrenheit. If the flowing fluid is water - then ρ f = ρ w, and (2) can be modified to How to determine the water pressure at depth 0m / 33ft, 1,000m / 3,300ft, 0.9bar / 0.9atm / 27.8psi 10m / 66ft, Sea level (0m / 0ft), 2bar / 2atm / 29.3psi. You can also convert psi to pascal, exapascal, petapascal, terapascal, gigapascal. G = acceleration of gravity ( 9.81 m/s 2, 32.174 ft/s 2) 1 psi 143.9997379997 lbf/ft / Convert psi to pound-force/square foot. Γ w = ρ w g = specific weight water (9807 N/m 3, 62.4 l b f/ft 3) Head loss as water column can be calculated by dividing the dynamic pressure with the specific weight of water like 1Psi 2.30897ftAq The pressure p in foot water (60f) (ftAq) is equal to the pressure p in psi (Psi) times 2.30897, that conversion formula: p (ftAq) p (Psi) × 2. Ρ f = density of fluid (kg/m 3, slugs/ft 3) Result : 1 Psi 2.30897 Foot Water (60F) How to convert Psi to Foot Water (60F) 1 psi (Psi) is equal to 2.30897 foot water (60f) (ftAq). P d = dynamic pressure in fluid (Pa, ps f (lb/ft 2)) The dynamic pressure in a fluid flow can be expressed as
