I have conducted wettability test of lithium ion batteries electrode using capillary rise test and wetting balance method based on Washburn equation measuring the capillary rise in the first one and mass change on the wetting balance method. when I apply curve fitting to get the wetting rate "K" for both tests individually from the slope, should these wetting rates (K) should be same or equal? I have used same electrolyte and electrode sample for both methods but different experiments.
