Abstract
The capillary rise of a perfectly wetting fluid, between two parallel plates (2 R apart), depends on the thickness of the wetting film. Moldover and Gammon (1) proposed a reduction of the effective spacing between plates 2 Reff (to be included in Jurin's law) such that R 2014 Reff is exactly equal to Z(h) (the thickness of a film spread on a single plate). We show that the film is thickened due to the second plate, and that R - Reff = 1.5 Z(h). The comparison between theory and the data of Moldover and Gammon on SF6 is thereby improved. The present analysis is restricted to non-retarded Van der Waals forces. Tome 45Keywords
