Common Questions
Is flow rate the same as fluid speed?
No. Volumetric flow rate measures volume per time. Fluid speed also depends on the pipe or channel cross-sectional area.
Are US gpm and Imperial gpm the same?
No. The Imperial gallon is larger, so the same numerical gpm value represents more volume than US gpm.
Does converting a pump rating predict its actual flow?
No. Unit conversion is exact, but actual pump flow depends on pressure, head, piping resistance, fluid properties, and equipment condition.
