A batch settling experiment is performed in a long column using a dilute dispersion containing equal number of particles of type A and type B in water (density 1000 kg m-3) at room temperature.
Type A are spherical particles of diameter 30 μm and density 1100 kg m-3.
Type B are spherical particles of diameter 10 μm and density 1900 kg m-3.
Assuming that Stokes' law is valid throughout the duration of the experiment, the settled bed would
A
consist of a homogeneous mixture of type A and type B particles
B
consist of type B particles only
C
be completely segregated with type B particles on top of type A particles
D
be completely segregated with type A particles on top of type B particles

Correct : a
