Abstract:
1. A method for measuring the dynamic viscosity and the density as physical quantities of an essentially non-compressible measuring medium, the method comprising: introducing a non-compressible measuring medium in a vessel charged with a compressible medium, wherein the non-compressible measuring medium constitutes a fraction volume of a total volume of the vessel; measuring an initial pressure of the compressible medium; modifying the total volume of the vessel by a predetermined modification volume; measuring a modification internal pressure of the compressible medium in the vessel effected by the volume modification; and causing a liquid measuring medium to flow through at least one opening of the vessel through a capillary tube, wherein the modification internal pressure is measured at least at one measuring point and wherein the initial pressure of the compressible medium surrounding the liquid measuring medium is measured after discharge out of the capillary tube.
