Apparent Particle Density
The apparent particle density is the density of individual particles, including their porosity.
Equation 1 : Apparent particle density
It is possible to calculate the apparent particle density from the Skeletal densityand the porosity which can be measured via pycnometry.
Equation 2 : Apparent particle density from skeletal density and porosity
ρp = apparent particle density (kg/m3)
ρsk = skeletal density (kg/m3)
ωp = porosity (m3/kg)
The particle density is used in applications requiring fluidization of particles or their suspension.
