1. Definition
What is the apparent particle density ?
The apparent particle density is the density of individual particles, including their porosity.
2. Calculation
How to calculate the apparent particle density ?
Equation 1 : Apparent particle density
3. Measurement
How to measure the apparent particle density ?
It is possible to calculate the apparent particle density from the Skeletal density and the porosity which can be measured via pycnometry.
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)
