Discuss the sedimentation in Brownian motion and show that during sedimentation, particle concentration decreases exponentially as height increases.
The phenomenon that Brownian particles attain a certain velocity under the action of an external field. This translational velocity is referred to as the sedimentation or settling velocity. The most common example of an external field is the earth’s gravitational field. For small particles, the sedimentation velocity in the earth’s gravitational field is very small, and sedimentation can only be observed by artificially increasing _____ _________ __________ _______ _________ _________ ______ ________ _________ ___.
