a)The company treats silica particles with a special

fluid in a 100 m3 tank before they can be used.

What is the settling velocity of the spherical clay particles of diameter 50 μm if the

volume fraction of the particles in the solvent is 0.4 and the only external force is

the gravity?

The density difference between the clay particles and solvent is 2400kg/m3; the

density and viscosity of the solvent are 1100kg/m3 and 10-2 Pa.s, respectively.

The exponential constant is 3 and CD=0.6.
