Theoretical model has been proposed for the calculation of concentration of a suspension discharging at the top from a mixed vessel. It has been assumed that no separation of solids occurs during sampling near the level and that the samples provide local values of concentration obeying the diffusional model. The model has been tested on experiments involving a cylindrical vessel with baffles mixed by a propeller impeller.
