Determination of bulk density pdf

Bulk density and tapped density of powders bulk density the bulk density of a powder is the ratio of the mass of an untapped powder sample and its volume including the contribution of the interparticulate void volume. This paper provides the verification of coefficients for the calculation of particle density, bulk density, and total porosity based on the texture of soils proposed by brogowski 1990.
