Abstract
When a two phase mixture containing solids dispersed in a liquid medium is continuously fed and withdrawn from a mixing tank then, at steady state, the concentration of solids in the tank will equal the inlet and outlet concentrations only at the conditions of isokinetic withdrawal where the velocity in the withdrawal tube is the same as the approach velocity at the tip of the discharge opening. For a preferred withdrawal position the data is analysed to give an empirical correlation from which the steady state concentration of solids in the tank can be calculated if the withdrawal velocity is known for glass beads-water system stirred in a tank using turbine type mixing impeller.
