Terminal Velocity Calculator (Stoke’s Law)
Calculate the terminal velocity of a spherical particle in a viscous fluid using:
\[
v_t = \frac{2\,r^2\,(\rho_p – \rho_f)\,g}{9\,\mu}
\]
where:
– \(r\) is the particle radius (m),
– \(\rho_p\) is the particle density (kg/m³),
– \(\rho_f\) is the fluid density (kg/m³),
– \(g\) is the acceleration due to gravity (m/s²), and
– \(\mu\) is the dynamic viscosity (Pa·s).
