Air Pipe Sizing Formula |
||
|
\( d \;=\; 24 \cdot \sqrt{ \dfrac{ Qa }{ 60 \cdot \pi \cdot v_a } } \) (Air Pipe Sizing) \( Q_a \;=\; 60 \cdot \pi \cdot v_a \cdot \left( \dfrac{ d }{ 24 } \right)^2 \) \( v_a \;=\; \dfrac{ Q_a }{ 60 \cdot \pi \cdot \left( \dfrac{ d }{ 24 } \right)^2 } \) |

| \( d \) = pipe inside diameter | \(in\) | \(mm\) |
| \( Q_a \) = air flow rate | \(ft^3 \;/\; min \) | \(m^3 \;/\; min \) |
| \( v_a \) = air velocity | \(ft \;/\; sec \) | \(m \;/\; s \) |
| \( \pi \) = Pi | \(3.141 592 653 ...\) | \(3.141 592 653 ...\) |
