25 lis 2010 · A head of 64 ft can be converted to pressure by using the second table: 64 ftH2O = 27.7 psi (lb/in2) Pressure in pounds per square inch (psi) vs. head in feet of water (ft h2o).
To convert head in feet to pressure in pounds per square inch (PSI): multiply by .433. Example: a 300' length of 1" plastic pipe runs from an inlet point to a point to discharge 40 feet lower. The approximate flow rate would be 40 x 100 divided by 300 = 13.3.
In infrastructure hardening, particularly when sealing against water, field professionals may be required to calculate water head pressure. This paper explains how to calculate water head pressure to help project planning. 1. Clarify how to measure water head pressure, and. 2. Provide simple measurement instructions.
WaterHead can be measured as vertical distance (feet or meters) or as pressure (pounds per square inch, newtons per square meter, etc.). Regardless of the size of your stream, higher head will produce greater pressure—and therefore higher output—at the turbine.
Pressure/Head. The pressure exerted by water or wastewater is directly proportional to its depth or head in the pipe, tank, or channel. If the pressure is known, the equivalent head can be calculated by: Head, ft = Pressure, psi x 2.31 ft/psi . Example: The pressure gauge on the discharge line from the influent pump reads 75.3 psi.
25 lis 2010 · Hydrostatic pressure in a liquid can be calculated as. p = ρ g h (1) where. p = pressure in liquid (N/m2, Pa, lbf /ft2, psf) ρ = density of liquid (kg/m3, slugs /ft3 ) g = acceleration of gravity (9.81 m/s2, 32.17405 ft/s2) h = height of fluid column - or depth in the fluid where pressure is measured (m, ft)
25 lis 2010 · Converting head in feet to pressure in psi. Pumps characteristic curves in feet of head can be converted to pressure - psi - by the expression: p = 0.433 h SG (1) where. p = pressure (psi) h = head (ft) SG = specific gravity of the fluid. Converting head in metre to pressure in bar
