Title (EN) KINEMATIC VISCOMETER AND METHOD
(FR) VISCOSIMÈTRE CINÉMATIQUE ET PROCÉDÉ ASSOCIÉ
Abstract: front page image
(EN) A viscometer assembly includes a first plate with a rail configured to constrain fluid thereon between its edges by surface tension. A second opposing plate has a surface spaced from the rail by a predefined gap of constraining fluid to the rail by surface tension when the rail is inclined and gravity pulls the fluid along the rail. The kinematic viscosity of the fluid is determined as a function of the predetermined gap and the time it takes the fluid to flow along the rail.
(FR) L'invention porte sur un ensemble viscosimètre comprenant une première plaque ayant un rail configuré pour contraindre un fluide sur celui-ci, entre ses bords, par tension superficielle. Une seconde plaque opposée a une surface espacée du rail d'un espace prédéfini de contrainte de fluide sur le rail par tension superficielle lorsque le rail est incliné et que la gravité tire le fluide le long du rail. La viscosité cinématique du fluide est déterminée en fonction de l'espace prédéterminé et du temps que met le fluide pour s'écouler le long du rail.
