Résumé

On décrit un appareil pour la détermination du coefficient de viscosité de l'eau au voisinage d'une surface de quartz transparent. On applique ici une variante de la loi de Stefan-Reynolds. Le coefficient de viscosité relatif de l'eau entre deux plaques de quartz transparent maintenues à seulement 100 Å l'une de l'autre est de plus de 10 pour les faibles contraintes de cisaillement. Des contraintes de cisaillement croissantes déterminent des valeurs plus faibles du coefficient de viscosité relative, et l'on peut donc admettre que l'eau, sous forme de ces couches très minces, se caractérise par un écoulement non newtonien.

Summary

An apparatus for the determination of the viscosity coefficient of water in the neighbourhood of a quartz glass surface is described. The law of Stefan-Reynolds is applied in a special modification. The relative viscosity coefficient of water between two quartz glass plates having a distance smaller than 100 Å lies beyond 10 for small shearing stresses. Increasing shearing stresses lead to smaller values of the relative viscosity coefficient of such water zone, so that a non-Newtonian behaviour of flowing water in very thin layers can be accepted.
