is the inside diameter at the discharge point. The size of this orifice is determined by the application involved and must be large enough to permit the solids that have been classified to underflow to exit the cyclone without plugging. The normal minimum orifice size would be 10% of the cyclone diameter and can be as large as 35%.

Hydrocyclone

A hydrocyclone (often referred to by the shortened form hydroclone or cyclone) is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance.This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles.
