Dynamic viscosity of air at 27c
WebThe viscous forces are characterized by the dynamic viscosity coefficient mu times the second gradient of the velocity d^2V/dx^2. The Reynolds number Re then becomes: Re = (r * V * dV/dx) / (mu * d^2V/dx^2) The gradient of the velocity is proportional to the velocity divided by a length scale L. Similarly, the second derivative of the velocity ...

Sutherland provides an … WebJan 26, 2016 · With an increasing altitude, the density of the air decreases. The dynamic viscosity decreases with an increasing altitude of up to $11'000~m$, then stays constant to $25'000~m$ and increases from an altitude of more than $25'000~m$. This is based on Sutherland's Formula for ideal gases, which in turn relies on the air temperature.
