Calculate Terminal Velocity (v)









Formula

The formula to calculate the terminal velocity (v) is:

\[ v = \frac{g \cdot d^2 \cdot (P - p)}{18 \cdot u} \]

What is Stokes' Law?

Stokes' law defines the terminal velocity of a falling object through a specific fluid or medium. It is used to describe the motion of spherical particles in a fluid and is crucial in fields such as fluid dynamics and engineering.

Example Calculation

Consider an example where:

Using the formula to calculate the terminal velocity:

\[ v = \frac{9.81 \cdot 0.01^2 \cdot (2500 - 1000)}{18 \cdot 0.001} = 81.75 \text{ m/s} \]

This means that the terminal velocity for this example is 81.75 m/s.
