Calculate Settling Velocity (V)







Formula

The formula to calculate the Settling Velocity (V) is:

\[ V = \frac{g \cdot \left(\frac{ps}{pf} - 1\right) \cdot d^2}{18 \cdot v} \]

Where:

Definition

Example

Let's say the density of the solid (ps) is 2500 kg/m³, the density of the fluid (pf) is 1000 kg/m³, the diameter of the solid (d) is 0.01 m, and the kinematic viscosity (v) is 0.001 m²/s. Using the formula:

\[ V = \frac{9.81 \cdot \left(\frac{2500}{1000} - 1\right) \cdot 0.01^2}{18 \cdot 0.001} = 0.08 \]

So, the Settling Velocity (V) is 0.08m/s.
