Air Pipe Sizing
Air Pipe Sizing formula
| \(\large{ d = 12 \; \sqrt { \frac { 4 } { \pi } \; \frac { Q_a } {60 \; v_a} } }\) |
Where:
| Units | English | Metric |
| \(\large{ d }\) = pipe inside diameter | \(\large{in}\) | \(\large{mm}\) |
| \(\large{ Q_a }\) = air flow rate | \(\large{\frac{ft^3}{min} }\) | \(\large{\frac{m^3}{min} }\) |
| \(\large{ v_a }\) = air velocity | \(\large{\frac{ft}{sec} }\) | \(\large{\frac{m}{s} }\) |
| \(\large{ \pi }\) = Pi | \(\large{3.141 592 653 ...}\) | |
