Understanding Centrifugal Force. Centrifugal force is the apparent force that acts outward on a mass moving in a circular path and is directed away from the center of rotation. This force is a result of the inertia of the rotating body, which tends to move in a straight line unless acted upon by another force, in this case, the centripetal ...

The radial force generated by the spinning rotor is expressed relative to the earth's gravitational force and therefore is known as the relative centrifugal force (RCF) or the "g force." The g force acting on particles is exponential to the speed of rotation (defined as revolutions per minute; rpm).

Centrifugal separation can be regarded as an extension of gravity separation, as the settling rates of particles are increased under the influence of centrifugal force. It can, however, be used to separate emulsions which are normally stable in a gravity field. Centrifugal separation can be performed either by hydrocyclones or centrifuges.
