# Air Velocity through Piping

## Air Velocity through Piping formula

\(\large{ v_a = \frac { Q_a }{ 60 \; \pi \; { \left( \frac {d}{24} \right) ^2 } } }\) |

### Where:

\(\large{ v_a }\) = air velocity

\(\large{ Q_a }\) = air flow rate

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

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