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,空气的粘度为1.81 × 10-5 kg/(m·s) ,18.1 μPa·s或1.81 × 10-5 Pa·s。
The kinematic viscosity of air at 15 °C is 1.48 × 10-5 m2 /s or 14.8 cSt. At 25 °C, the viscosity is 18.6 μPa·s and the kinematic viscosity 15.7 cSt.
15 °C时,空气的运动粘度为1.48 × 10-5 m2 /s或14.8 cSt。在25℃时,粘度为18.6 μPa·s,运动粘度为15.7 cSt。
