Density tapped
WebTapped density is very useful and popular as an indicator of the flow properties of powders and is used to calculate Hausner ratio and Carr’s index. 16.5.3.1. Hausner ratioThis is the ratio of the poured density to the tapped density. Hausner showed that free-flowing powders (with low interparticular friction) had a ratio of less than 1.2 ... Web2.9.34. 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 to its volume, including the contribution of the interparticulate void volume. Hence, the bulk density depends on both the density of powder particles and the spatial arrangement of particles …
