aeration number 1Aeration Number, abbreviated as \(N_a\), a dimensionless number, is used for the agitated mixing of gas and liquids.


Aeration Number formula

\(\large{ N_a = \frac{ Q }{ n \; d^3 }  }\)   


\(\large{ N_a }\) = Aeration number

\(\large{ Q }\) = volumetric flow rate of gas

\(\large{ n }\) = rotational speed

\(\large{ d }\) = diameter of impeller
