Terminal velocity calculator

Back to Utilities

This utility calculates the terminal velocity, Reynolds number and drag coefficient of a spherical particle. The forces accounted for are drag, buoyancy and gravity. Various drag models are available.

Diameter d_p [m]

Particle density ρ_p [kg/m³]

Fluid density ρ_f [kg/m³]

Dynamic viscosity μ [Pa·s]
