Tapped Density - an overview | ScienceDirect Topics

Tapped density of a powder is the ratio of the mass of the powder to the volume occupied by the powder after it has been tapped for a defined period of time. The tapped density of a powder represents its random dense packing. Tapped density can be calculated using Eq. (10.3), where M=mass in grams, and V f =the tapped volume in milliliters.
