Pipe Flow Calculator

The above Flow Meter Calculator is compliments of Flow Meters SG

” This tool will calculate the volumetric flow rate in any units from the specified velocity of a substance flowing through a pipe. It will also calculate the velocity if you know the volumetric flow rate. Formula The volumetric flow rate formula used by this calculator is: Q = v · A Symbols.This formula assumes uniform flow conditions within the entire cross-sectional area, without any friction losses near to surfaces. Inside diameter Enter the pipe internal diameter in mm or inches Velocity Enter the pipe velocity if known Volumetric Flow Rate Calculation This is the amount of volume that will flow pass per unit of time.

The calculations give both metric and imperial unit results.”
