1. Definition

The apparent particle density is the density of individual particles, including their porosity.

2. Calculation

PowderProcess.net - Apparent particle density

Equation 1 : Apparent particle density

3. Measurement

It is possible to calculate the apparent particle density from the Skeletal densityand the porosity which can be measured via pycnometry.

PowderProcess.net - Apparent particle density calculation

Equation 2 : Apparent particle density from skeletal density and porosity

With :
ρp = apparent particle density (kg/m3)
ρsk = skeletal density (kg/m3)
ωp = porosity (m3/kg)


4. Application

The particle density is used in applications requiring fluidization of particles or their suspension.
