The theory of scaling up laboratory data for the sedimentation type centrifuge

Abstract

Abstract The mathematical theory of the sedimentation type of centrifuge is developed in terms of unhindered settling of a single particle that has reached equilibrium velocity. From this is derived the sigma value for several of the different forms of sedimentation type centrifuge which is the calculated equivalent area of a settling tank theoretically capable of doing the same amount of work in a unit gravitational field. The limitations controlling the accuracy of scale up between centrifuges of similar geometry and between centrifuges of substantially different geometry are discussed.
