Impellers
Flow coefficient is one such term. The flow coefficient of an impeller describes the volumetric flow passing through the compressor as a function of tip diameter and speed. It is given by Φ 1 = Q 1 D 2 3 N, where Q 1 is the inlet flow, D 2 is the tip diameter, and N is the rotational speed.
