12.4: Viscosity and Laminar Flow; Poiseuille's Law
Flow is proportional to pressure difference and inversely proportional to resistance: Q = P2 − P1 R. For laminar flow in a tube, Poiseuille's law for resistance states that R = 8ηl πr4. Poiseuille's law for flow in a tube is Q = (P2 − P1)πr4 8ηl. The pressure drop caused by flow and resistance is given by P2 − P1 = RQ.

Prediction of emulsion drop size distributions in colloid mills
Emulsions are usually prepared via a two step process. In the first step, a coarse emulsion or premix is prepared by thoroughly mixing the ingredients in a low shear device. The coarse emulsion is then passed through a high energy mechanical device such as a high pressure homogenizer or a colloid mill.
Emulsion stability basics | Processing Magazine
Using the same argument as before, a reduction in viscosity should lead to easier emulsion formation because of a reduced interfacial tension. While this is true, another factor must be considered. An increase in continuous-phase viscosity will greatly improve emulsion stability by retarding the inevitable rise of the oil droplets to the top.
Pigment Grind: How to Efficiently Adjust the Fineness
In the industry, the fineness of grind is generally achieved with a 2-step process. First, developers and producers of paints use a dissolver to reduce the particle size of their pigments and fillers to a certain degree of fineness. Then, when needed, they additionally use a pearl mill to further separate the solid particles from each other.

Understanding the Deflocculation Process in Slip Casting
Viscosity refers to the mobility of the slip; its "thickness" or "runniness". A slip that has high viscosity is thick like syrup and one that has low viscosity is fluid. A deflocculant is used to lower the viscosity of a slip (provided of course that the slip does not have so high a solids content that a deflocculant simply cannot thin it anymore).
