FORFARANDE OCH ANORDNING FOR KONTINUERLIG BESTEMNING AV VETSKORS VISKOSITET

摘要

The viscosity of a liquid is determined according to the capillary method, by establishing a constant liquid level within or above the capillary, and determining the liquid flow velocity through the capillary. A device for carrying out this process includes a capillary fitted with an inlet tube for introducing the liquor in the upper part (4) of the capillary, and an extraction tube (6) for drawing off excess of added liquid, as well as a device (9) for the determination of the amount of liquid leaving the lower end (7) of the capillary.
