Question

The settling velocity of inorganic particles in the sedimentation tank of a water treatment plant is governed by

Correct answer (B) Stokes’ law Solution The settling velocity of discrete inorganic particles in a fluid under laminar flow conditions is governed by Stokes' law, which relates the terminal velocity to the particle size, density, and fluid viscosity. Thus, the correct option is (B). Turn this into a strength. Explore AI-powered practice and doubt support with Success Tracker.
