# Water Velocity Through Piping

### Water Velocity Through Piping formula

\(\large{ v_w = \frac { 0.134 \; Q_w } { 3600 \; \pi \; { \left( \frac {d}{24} \right) ^2 } } }\)

Where:

\(\large{ v_w }\) = water velocity

\(\large{ \pi }\) = Pi

\(\large{ d }\) = pipe inside diameter

\(\large{ Q_w }\) = water flow rate
