Existence Theorems and Measurement of the Capillary Contact Angle

B.S. Fischer and Robert Finn[1]

(1) Stanford University, USA

In an earlier work, Concus and Finn proposed two procedures, based on a dichotomous, behavior of fluid in capillary tubes at zero gravity, designed for-accurate measurement of capillary contact angles. The present work offers modifications to one of their procedures which should facilitate the experiments and lead to improved accuracy. The discussion leads to explicit characterization of a capillary tube with "canonical" section, which has an independent mathematical interest.
