Dynamic Viscosity of Air 空气的动态粘度 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...
The higher the viscosity, the thicker (less liquid) the fluid; the lower the viscosity, the thinner (more liquid) it is. SI unit of dynamic viscosity:[η] = Pascal-second (Pa*s) = N*s/m² = kg/m*s Factors influencing dynamic viscosity ...

The dynamic viscosity can be calculated from kinematic viscosity by multiplication with density (kg/m3). Ideal fluids exhibitNewtonian flow, thus the viscosity is constant for any applied shear stress. If the viscosity of fluids is increasing with shear stress, they are calleddilatant;if it is de...
μ = absolute or dynamic viscosity (N s/m2) ρ = density (kg/m3) In the SI-system the theoretical unit of kinematic viscosity ism2/s- or the commonly usedStoke (St)where 1 St (Stokes) = 10-4m2/s = 1 cm2/s Stoke comes from the CGS (Centimetre Gram Second) unit system. ...
