effective drop size. Thus the emulsion may be flocculated.

The same calculation procedure with Eq. [3.41] can be applied to upper front
of sample 3 using the data of Figure 3.23. Here φ_e is 0.50. The experimental
sedimentation velocity of water droplets is 0.044 cm∕h, whereas the predicted
value is 0.0103 cm∕h. Their ratio is about 4:1, indicating that there likely some
flocculation in this case as well. However, further investigation of flocculation in
these emulsions is desirable.
