Settling Velocity in Displacement and Drag Formulas

The Settling Velocity refers to the rate at which a particle suspended in a fluid (like water or air) falls under the influence of gravity until reaches a constant speed. And is denoted by V_s. Settling Velocity is usually measured using the Meter per Second for Speed. Note that the value of Settling Velocity is always positive.
