How to determine water psi
WebA hydrant flow test evaluates the water supply to determine what flow rate will be available at 20 psi residual. A hydrant flow test requires three measurements: static pressure, residual pressure and test flow rate. The reading from the gauge cap on the test hydrant gives you static and residual pressures. WebFeb 20, 2024 · The total pressure, or absolute pressure, is thus the sum of gauge pressure and atmospheric pressure: (11.6.1) P a b s = P g + P a t m. where P a b s is absolute pressure, P g is gauge pressure, and P a t m is atmospheric pressure. For example, if your tire gauge reads 34 psi (pounds per square inch), then the absolute pressure is 34 psi plus …
