Particle Stopping Distance Calculator

This tool calculates the distance covered by a moving spherical particle or spherical object having an initial velocity to come to rest in stationary air due to drag force with zero gravity.



Type the required values to get the stopping distance:

Air Viscosity (µf, kg/ms)


Particle Density (ρ, kg/m3)


Particle Diameter (Dp, m)


Particle Initial Velocity (uo, m/s)




Particle Stopping Distance (m)


Particle Relaxation Time (s)
