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 ... WebMar 29, 2015 · The properties of Air have been tabulated below, listed by temperature in ascending order.
