# Water Flow Rate through Piping

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

## 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
