Wet Particle Specific Gravity
No consensus-based definition and methodology for wet particle
specific gravity WPSG exist in the literature. Particles are usually
dried in an oven to measure specific gravity SG. However,
the drying step may significantly change particles’ physicochemical
characteristics i.e., size, modifying settling behavior of particles

reasonable parameter to represent the particle density determining
