A mathematical model is described for isothermal flow of Newtonian liquids through stacked‐disc filters. Dimension‐less flow rates, velocities through filter media, pressure distributions, and internal forces are shown as functions of resistance ratios and reduced dimensions. The distribution of velocities through the media is a strong function of the ratios of the resistances to flow through the gaps between discs and through the spaces inside the discs to the resistance to flow through the filter media. Internal forces compress the discs and can, in exceptional cases, impair the media and open up leakage passages.
