Fig. 6From: An experimental study on the rate and mechanism of capillary rise in sandstoneMeasured and calculated values of capillary rise over time. Examples of capillary rise curves calculated using the L-W equation under the conditions of r = 10 μm and cosθ = 1 or 0.59 and best fit curves following the L-W equation at cosθ = 1 or 0.59Back to article page
