# Water Flow Rate through Piping

## Formulas that use Water Flow Rate through Piping

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

### Where:

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

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

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

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