Sedimentation Rate P

Sedimentation Rate - an overview | ScienceDirect Topics

The sedimentation rate depends on particle buoyancy (the difference between the density of the particles and the density of the liquid), the viscosity of the liquid, and the size of the particles. The net force acting on a particle suspended in a liquid is the difference between the gravitational force F g and the drag force F d (3.C.1).

Sedimentation Rate Definition & Normal Range - MedicineNet

A sedimentation rate is common blood test that is used to detect and monitor inflammation in the body. The sedimentation rate is also called the erythrocyte sedimentation rate because it is a measure of the red blood cells (erythrocytes) sedimenting in a tube over a given period of time. Sedimentation rate is often abbreviated as "sed rate" or ESR.

Basic Theory of Particle Size Analysis by Sedimentation

rate of sedimentation for small particles is too low to give a practical analysis time, and because Brownian motion of small particles becomes too large to allow effective settling. A very narrow distribution of small particles will be reported as a broad distribution when the rate of particle diffusion is comparable to the sedimentation rate.
