Abstract Flow equations have been proposed for hydroextractor cakes wherein the pores are filled with moving liquid. These equations have been confirmed for the effect of each variable by use of different experimental techniques. The critical wetting rate has provided the most informative steady state, in which the cake is fed with liquid to maintain the inner surface of the liquid at radius r L coincident with that of the cake at radius r c . Transient techniques have also been used wither with a probe to time the movement of a liquid level between two radii less than r c , or with a photoelectric detector to observe the coincidence of r L = r c . The tests have proved the validity of the hydrodynamic assumptions involved in the equations and have provided both precise methods for research and practical methods for industrial purposes.
