Volume viscosity (also called bulk viscosity, second coefficient of viscosity, or dilatational viscosity) is a material property relevant for characterizing fluid flow. Common symbols are, ′,, has dimensions (mass / (length × time)), and the corresponding SI unit is the pascal-second (Pas).. Like other material properties (e.g. density, shear viscosity, and thermal conductivity. Conductivity and Resistivity Values for Misc.

The importance of thermophysical properties data for fluids involved in cryogenic processing is generally recognized within the engineering community. Cryogenic fluid properties have played. The model predicts a value for the heat capacity ratios of γ = 4 / 3, which is slightly smaller than the value γ = 7 / 5 for nitrous oxide. Therefore, the rough sphere model predicts a wrong value for the speed of sound and this is crucial in producing good agreement with by: 3.

The dimensionless ratio f = λM/ηC v relating the thermal conductivity, molecular weight, viscosity, and constant‐volume molar heat capacity has been determined experimentally for helium, argon, nitrogen, oxygen, and hydrogen in the range 90°–°K. The experimental method provides a direct determination of f by measurement of the subsonic temperature recovery factor. Data for the viscosity and thermal conductivity coefficients of argon, nitrogen, and oxygen have been critically evaluated. A functional form to represent the data has been proposed. The function is basically the same for both coefficients. The critical point enhancement in the thermal conductivity coefficient is included. Transport properties of krypton and xenon are calculated by .

It corresponds roughly to the intuitive notion of a fluid's 'thickness'. For instance, honey has a much higher viscosity than water. Viscosity is measured using a viscometer. Measured values span several orders of magnitude. Of all fluids, gases have the lowest viscosities, and thick liquids have the highest.
