A new model for capillary rise in nano-channels offers insights into improved hydraulic fracturing (fracking)

With fracking, scientists have calculated the expected level of capillary rise with the Lucas-Washburn equation, a mathematical model whose earliest parameters were first devised nearly a century ago. The challenge, however, is that that the equation has not been completely accurate in predicting the actual rise observed in nano-capillary laboratory experiments.
