  "term": "Equivalent diameter",
  "field": "Chemistry",
  "definition": "The diameter of a hypothetical spherical particle that exhibits the same value for a specific physical property as an irregularly shaped particle under consideration. This property can be related to its volume, surface area, or aerodynamic behavior, such as its terminal settling velocity in a fluid. For atmospheric aerosols, the Stokes diameter is a common equivalent diameter based on aerodynamic properties.",
