Moreover the density is an essential part of the working equation used to determine the viscosity from the measuring signal, regardless of the type of viscometer. An apparatus for the simultaneous measurement of viscosity and density of fluids is presented. The main element of the instrument is ...
Viscosity is an important fluid property when analyzing liquid behavior and fluid motion near solid boundaries. The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. The shear resistance in a fluid is caused by inter-molecular friction e...

down to 2.2 K. At that point, it becomes what is known as a superfluid. There is zero viscosity and friction at this temperature. That means if you stir something which demonstrates superfluidity, it will never stop rotating.

The model treats a pressure drop or loss that depends on the pressure difference across the gauge (P1-P2), the fall rate of the piston, the density of the gas and the viscosity of the gas. The model was tested using helium, neon, argon, nitrogen and krypton, and several values of (...
