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.

Centrifugation: Theory, Sedimentation Rate, Coefficient ...

The instantaneous sedimenta­tion rate of a particle during centrifugation is deter­mined by three forces: (1) F C, the centrifugal force, (2) F B, the buoyant force of the medium, and (3) F F, the frictional resistance to the particle's movement.. Equation 12-13 is very important to the understand­ing of particle sedimentation and should be carefully examined, for the equation shows that ...

Sedimentation - water.me.vccs.edu

Weir loading, also known as weir overflow rate, is the number of gallons of water passing over a foot of weir per day. The standard weir overflow rate is 10,000 to 14,000 gpd/ft and should be less than 20,000 gpd/ft. Longer weirs allow more water to flow out of the sedimentation basin without exceeding the recommended water velocity.
