Question

According to soil mechanics what is stoke's law and its limitations

Answer 1

Stoke's Law uses known properties of a particle and a fluid to determine the velocity of a particle when its propelling force is exactly matched by the resistance of the fluid's viscosity. The most frequent force used is gravity, although it could be anything. When the conditions for the validity of Stoke's Law are not met, such as when the particle is very large or fast moving, so that the flow of the fluid around the particle is turbulent rather than smooth, Newton's Resistance Law applies instead.
