Problem 11.2. Hindered Settling Velocity

Solution Using the preceding equation for the terminal hindered settling velocity for laminar flow. 

Therefore the sedimentation velocity of a ceramic suspension with a hi volume fraction is less than that of a sin e particle. 

The combined effects of nonspheiical shape and hindered settling can be approximated by combining these two effects as follows  

This equation is only a first-order approximation good for the lower volume fractions because the particles will orient themselves, thus lowering their lateral volume fraction.
