A more accurate characteristic is a cut size (dpc), which is defined as a particle size for which the efficiency is 50%. This particle size can be calculated approximately by equating the centrifugal force on a particle (due to its angular velocity) to the drag on the particle due to the radial gas velocity (Dietz, 1981).
