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 through a fluid. It was developed by George Gabriel Stokes, and has widespread applications.

Answer and Explanation:

Stokes' Law is valid for determining viscosity when velocity is constant. When a sphere reaches its terminal velocity, the force of friction equals...
