Aerodynamic Diameter Calculator

This tool calculates the aerodynamic diameter of an irregular shape particle or object. Aerodynamic diameter is defined as the diameter of a water droplet falling under gravity in air having the same settling velocity as that of the irregular shape particle.

Type the required values to get the aerodynamic diameter:

Particle mass (m, kg)

Particle Density (ρ, kg/m3)

Air Density (ρair, kg/m3)

Aerodynamic Diameter (m)

Terminal velocity (m/s)
