Air Flow Rate through Piping

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Air Flow Rate through Piping formula

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

Where:

 Units English Metric
\(\large{ Q_a }\) = air flow rate \(\large{\frac{ft^3}{sec}}\) \(\large{\frac{m^3}{s}}\)
\(\large{ v_a }\) = air velocity \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
\(\large{ \pi }\) = Pi \(\large{3.141 592 653 ...}\)
\(\large{ d }\) = pipe inside diameter \(\large{ in }\) \(\large{ mm }\)
