In 1851 , George Gabriel Stokes derived an expression for the Friction al Force exerted on spherical objects with very small Reynolds Number s (e.g., very small particles) in a Viscous Fluid by solving the generally unsolvable Navier-Stokes Equations : : where: F r :η is the fluid viscosity, and v If the particles are falling in the viscous fluid by their own weight, then we can derive their settling velocity by equating this frictional force with the Gravitational Force : : where: Vs g ρp ρf SEE ALSO |
