Consequently, if a liquid has dynamic viscosity of n centiPoise, and its density is not too different from that of water, then its kinematic viscosity is around n centiStokes. For gas, the dynamic viscosity is usually in the range of 10 to 20 microPascal-seconds, or 0.01 to 0.02 centiPoise. The density is usually on the order of 0.5 to 5 kg/m^3.
The proportionality factor is the dynamic viscosity of the fluid, ... the viscosity of air depends mostly on the temperature. ... Ethanol: 1.074 × 10 −3:
Viscosity [3] 6.285 mPa·s: at −50 °C 4.656 mPa·s: at −40 °C ... Vapor–liquid equilibrium of the mixture of ethanol and water (including azeotrope)
where is the dynamic viscosity of the liquid, is a characteristic velocity and is the surface tension or interfacial tension between the two fluid phases. Being a dimensionless quantity, the capillary number's value does not depend on the system of units.
The turbulent Schmidt number is commonly used in turbulence research and is defined as: [3] = where: is the eddy viscosity in units of (m 2 /s); is the eddy diffusivity (m 2 /s).; The turbulent Schmidt number describes the ratio between the rates of turbulent transport of momentum and the turbulent transport of mass (or any passive scalar).
The dilute gas viscosity contribution to the total viscosity of a fluid will only be important when predicting the viscosity of vapors at low pressures or the viscosity of dense fluids at high temperatures. The viscosity model for dilute gas, that is shown above, is widely used throughout the industry and applied science communities.
The propensity of a fluid to swirl is used to promote good fuel/air mixing in internal combustion engines. ... and μ is the dynamic viscosity of the fluid. A ...
