Overview
Short
Long
This calculator can be used to determine the fluid velocity (Vf) inside a pipe for a given flow rate (Q) and pipe diameter (D) (or vice versa).If you enter any two of these variables as inputs, the calculator will determine the third variable.
Input 2 of 3 variables to solve for the unknown.
