Calculate Diameter Of a Particle



App description

Stokes's calculation: terminal velocity, acceleration of gravity, diameter of a particle, density of medium, density of particle, viscosity of medium

Calculation of terminal velocity, acceleration of gravity, diameter of a particle, density of medium, density of particle, and viscosity of medium.

Select the appropriate unit and enter a value and click on "Calculate". The result will be displayed.

Calculation formula

D = Diameter Of a Particle

V = Terminal Velocity

v = Viscosity Of Medium

g = Acceleration Of Gravity

dp = Density Of Particle

dm = Density Of Medium

\(D=√\frac {18×v×V}{g×d _p-d _m)}\)

Usage example

Known data: viscosity of medium; terminal velocity; acceleration of gravity; density of particle; density of medium, what is the diameter of a particle?

Input data: viscosity of medium : 15 g / m - sec; terminal velocity: 25 m/s; acceleration of gravity: 10 m / sec; density of particle : 5 g / m3; density of medium :2 g / m3, click "Calculate" ,show results.

Output: The diameter of a particle is 15.0000 m / s.

Note

The unit of acceleration of gravity, diameter of a particle, density of particle, density of medium, and viscosity of medium can be checked. Click the arrow in the check box to select the corresponding unit.
