Describing liquid penetration into paper with Lucas-Washburn equation For liquids, their penetration into paper is usually more important than the flow through paper. The penetration takes place by capillary flow into effective capillaries. The Lucas-Washburn equation often finds use in the analysis of liquid penetration into paper. One can derive the Lucas-Washburn equation from the
