According to this law attenuation of sound α is proportional to the dynamic viscosity η, square of the sound frequency ω, and reciprocally proportional to the fluid density ρ and cubic power of sound speed V, Attenuation is expressed in neper per meter in this equation. The author of ...
Stokes Law, Viscosity. (very simple) I'm trying to find the viscosity of some glycerol that we dropped various steel balls down using the equation: V = [2r^2 (p –σ) g] / 9η I put in these values: p = 7800 kg m-3 σ = 1200 kg m-3 g = 9.8 m s-2 And ended up wit...

To analyze equation (12), (13) and (14) it is convenient to rewrite the unknown terms in the following way: (17)(18)(19)(20)Where the perfect gas relations (8) and Fourier's law (6) have been used. Note also that fluctuations in the molecular viscosity, , have been neglected. ...
The Sullivan vortex model has also been used widely to model tornado-like flows. As in the case of the Burgers–Rott model, we consider a flow that is stationary, with constant viscosity and zero body forces. In addition, it is considered that velocity components are given in the formu=u...
Under what condition is Stokes' Law valid for the determination of dynamic viscosity?Question:Under what condition is Stokes' Law valid for the determination of dynamic viscosity?Stokes' Law:In physics, Stokes' law relates the force of friction (or drag) as a sphere moves t...
Here, u is the velocity of the fluid, t is time, ν is the kinematic viscosity, g is gravity (or external body force), and w=P/ρ, where P is the pressure and ρ is the mass density. The left-hand side terms of the equation represent local variation of the velocity field and it...
In the consequence the pressure solution of the continuity equation must have a jump across the streamline emanating from the cut tip. We establish a piecewise regularity of the solution by the corner singularity and the contact singular function....
