Question

the particle size decrease sedimentation rate is​

Answer 1

Answer:

When particles are typically smaller than about a = 10 − 100nm, sedimentation velocities in the earth's gravitational field are very small, and sedimentation experiments must be performed by centrifugation.

Answer 2

Answer:

When particles are typically smaller than about a =10- 100nm, sedimentation velocities in the earth's gravitational field are very small, and sedimentation experiments must be performed by centrifugation.
