On apparent bulk density of powder

On apparent bulk density of powder
The applicability and the properties of the constants of the following equation on the number of tappings and the apparent bulk density of the powder were studied. The equation is [function], where, n is the number of tappings, po, pf and pn are the apparent bulk densities of the powder at n=0, ∞ and n respectively, and k is a constant.
