WebThe following table gives the viscosity of some common gases as a function of temperature . Unless otherwise noted, the viscosity values refer to a pressure of 100 kPa (1 bar) . … WebAbstract. The paper describes measurements of the viscosity of helium in the range of pressures of 1137 atm and in the range of temperatures of 25237C with an accuracy of from 0.2% at lower temperatures to 0.5% at higher temperatures. The method used was that of a disk oscillating between two plates with moderate gaps, and the measurements were ... headset headphone

WebNov 8, 2024 · While Stokes’ hypothesis of neglecting bulk viscous effects is exact for monatomic gases and unlikely to strongly affect the dynamics of fluids whose bulk-to-shear viscosity ratio is small and/or of weakly compressible turbulence, it is unclear to what extent this assumption holds for compressible, turbulent flows of gases whose bulk viscosity is … WebSo you can see that the number of "viscosity coefficients" from 81 to 2.
