Question

Explain how can you correlate velocities of different sizes particles settling in fluid?​

Answer 1

Answer:

Blending and Agitation

Stephen Hall, in Branan's Rules of Thumb for Chemical Engineers (Fifth Edition), 2012

Terminal Settling Velocity

Calculate the settling velocity of the solids, adjusted for solids concentration. Use these equations to obtain the basic velocity [10]:

(16-17)ws=(A+

B

S∗

)−1

√

(s−1)gdN

Where:

S∗=

dN

4v

√

(s−1)gdN

ws = settling velocity, cm/s or ft/s

A,B = coefficients dependent on particle shape factor and roundness (see Table 16-10)
