Kinematic Viscosity of Air 空气的运动粘度 Prandtl Number Air 空气的普朗特尔数 The viscosity of air depends mostly on the temperature. At 15 °C, the viscosity of air is 1.81 × 10-5 kg/(m·s) , 18.1 μPa·s or 1.81 × 10-5 Pa·s . 空气的粘度主要取决于温度。在15℃时,空气的粘度...
Online calculators, figures and tables showing dynamic and kinematic viscosity of liquid and gaseous propane at varying temperarure and pressure, SI and Imperial units.
Online calculator, figures and tables with dynamic (absolute) and kinematic viscosity for air at temperatures ranging -100 to 1600°C (-150 to 2900°F) and at pressures ranging 1 to 10 000 bara (14.5 - 145000 psia) - SI and Imperial Units.
Therefore, we can relate these two proportionalities and derive the relationship between kinematic viscosity and temperature as ν = T3/2. As you can see now, when the temperature rises, the viscosity of the air increases. This distinguishes air and most gases from the viscosity of liquids. ...
Generally speaking, viscosity is a fluid’s resistance to flow (shear stress) at a given temperature. Sometimes, viscosity is erroneously referred to as thickness (or weight). Viscosity is not a dimensional measurement, so calling highly viscous oil thick and less viscous oil thin is misleading....
whereηis the viscosity of the polymer solution andη0is the viscosity of the pure solvent at the same temperature, as a function of polymer concentrationc. The relative viscosity thus reflects the increase in the viscosity imparted to the solution by the presence of polymer.Table 7.1summarizes...
Viscosity reporting is only valid when the temperature at which the test was conducted also is reported - for example 23 cSt at 40 degrees C. Of all the tests employed for used oil analysis, none provides better test repeatability or consistency than viscosity. Likewise, there is no property ...
*) at room temperature Absolute or Dynamic Viscosity of common Liquids . Kinematic Viscosity Kinematic viscosity is the ratio of- absolute (or dynamic) viscosity to density- a quantity in which no force is involved. Kinematic viscosity can be obtained by dividing the absolute viscosity of a fluid...
