Particle settling velocity is the rate at which a particle falls through a fluid under the influence of gravity, crucial for understanding sedimentation processes in natural and engineered systems. It is influenced by particle size, shape, density, and the fluid's viscosity and density, and is often described by Stokes' Law for small, spherical particles in a laminar flow regime.

Particle size is a critical parameter that influences the physical and chemical properties of materials, affecting their behavior in processes such as dissolution, sedimentation, and filtration. It is essential in fields like pharmaceuticals, materials science, and environmental engineering, where precise control over particle size distribution can impact product efficacy, stability, and environmental impact.

Particle density refers to the mass per unit volume of the solid particles in a material, excluding the volume of any voids or pores within the material. It is a crucial parameter in fields like soil science, material science, and engineering for understanding the composition and behavior of granular materials.
