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.
The increase in the work load of the respiratory muscles due to an increase in air humidity, and hence viscosity, from purely physical considerations, appears to be very small compared with the total work of breathing.P. D. RoyW. T. Josenhans...
aSlag viscosity was measured under air or reducing atmosphere (calculated pO2~1.2×10-12 atm at 1400°C) at temperatures in the range of 1150-1550°C on 63 statistically designed slags, 炉渣黏度在63统计地被设计的炉渣被测量了在空气或还原气层(故意的pO2~1.2×10-12 atm之下在1400°C)在温度...
Air Viscosity: Dynamic and Kinematic Viscosity at Various Temperatures and Pressures 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 - 14500...
The elusive transport coefficient, the bulk viscosity ηb, is effectively derived by a comparing the measurements to the model, yielding an increased trend from 1.0 to 2.5 × 105 kg ·m1 · s1 for the temperature interval. The calculated (Tenti S6) line shapes are ...

The dissipation of the energy of sound waves attributed to the medium in which they propagate, in this case air, is caused by three mechanisms: shear viscosity, thermal conductivity, and molecular relaxation. These represent different processes in which sound energy is converted into heat or intern...
where ∆p is the pressure change in the porous medium (Pa), R1 is the internal resistance factor, R2 is the viscous resistance coefficient, ρ is the density of air (kg·m−3), v is the velocity flowing in the porous medium (m·s−1), and μ is the viscosity coefficient of ...
Table 2.Particle interaction properties during interaction at certain points S-L-U-A′. 3.2. Numerical Modeling of Air Flows The laminar flow viscosity model was chosen, using the solution which converged, and residuals of 10−5order were achieved. A numerical model was developed to find repre...
