* The relative flow rate is a ratio of the cake thickness and time taken for a constant volume of water to pass through a constant mass of filter aid.
** The permeability cake is the ratio between the mass and the wet volume of the filter cake. A rule of thumb for perlite filter aids says that a higher cake density usually results from smaller particle size filter aid. To reduce the cake density the particle size of the filter aid must be increased.
*** A material having a permeability of 1 Darcy unit passes 1 ml per second per cm2 of a liquid of 1 centipoise viscosity through a cake of 1 cm thickness at a pressure differential of 1 atmosphere.
