Answer to Question #181409 in Mechanics | Relativity for Max

Question

Can you explain stokes law.

Answer 1

Answer:

Stokes' law - the statement that the force of resistance F, which meets a solid ball of radius R with slow uniform translational motion with a velocity in an unlimited viscous medium with a dynamic coefficient of viscosity (or in a laminar fluid flow), is equal to

 $F=6\pi R\eta v,$

• $F_D$ is the friction force acting on the interface between liquid and particles (in N),

•$\eta$ is an indicator of dynamic viscosity (N s / m 2)

• R is the radius of a spherical object (in m), and

• $v_s$ is the particle deposition rate (in m / s).
