Settling Velocity of Particle given Coeff of Drag is the velocity at which a particle settles in a fluid, such as water or air, under the influence of gravity, considering coefficient of drag. And is denoted by Vsc. Settling Velocity of Particle given Coeff of Drag is usually measured using the Meter per Second for Speed. Note that the value of Settling Velocity of Particle given Coeff of Drag is always positive.
