Calculate the terminal settling velocity of a spherical particle falling under gravity in a viscous fluid. Default values for a 100 micron sand particle in water are provided.
The calculators use a series of empirical correlations to obtain an engineering estimate of the quantities of interest. These values should only be used as first estimates and should be updated using more accurate and validated methods when designing or analysing real engineering or scientific systems. To see the formulas that are used in the calculators, consult the PDF below.
