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...
5) gas viscosity factor 气体粘滞系数6) viscous motion 粘滞运动 1. An internal friction peak associated with the viscous motion of interfaces in the Cu-Al-Zn-Ni alloy was measured by using the piezoelectric composite oscillator in 50-150 kHz range. 用静电激励法和压电组合振子法测量了Cu-...
For example, you can determine the kinematic viscosity of air if the dynamic viscosity and density are already known. In this calculator, we will learn more about viscosity, with a particular focus on the kinematic and dynamic viscosity of air. Keep reading to learn: What does viscosity mean?
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.
Example - Air, Convert between Kinematic and Absolute Viscosity Kinematic viscosity of airat1 bar (1 105Pa, N/m2)and40oCis16.97 cSt (16.97 10-6m2/s). The density of the air can be estimated with theIdeal Gas Law ρ = p / (R T) ...
viscosity may disturb the fuel flow rate during intake stroke, which delays the mixing of air and fuel in the combustion chamber (Dharmaet al., 2016). Kinematic viscosity for most of the biodiesels ranges between 3 mm2/s and 5.5 mm2/s at 40°C, but for castor oil biodiesel it is ...

Dynamic viscosity is measured as the resistance to flow when an external and controlled force (pump, pressurized air, etc.) forces oil through a capillary (ASTM D4624), or a body is forced through the fluid by an external and controlled force such as a spindle driven by a motor. In eith...
Please, remember that at low pressures, a decrease in temperature causes the viscosity of a gas at low density to decrease while it causes the viscosity of a liquid to rise. At high pressures, an increase in temperature causes a decrease in viscosity of a gas. The viscosity of liquids ...
Degradation of saliva after sampling affects viscosity and slightly pH. The use of capillary viscometer to evaluate salivary aging needs more improvements. Further studies are required to investigate and explain the effects of different techniques to reduce the film forming on the air/liquid interface ...
