| 1. A method of calculating and controlling the viscosity of a shear-thinnable fluid stream at a particle-forming section of
a dispersion device by:
a) providing a measured static head of shear-thinnable fluid within the dispersion device;
b) providing a pressurized blanket of inert gas over the fluid at a measured gas pressure;
c) mechanically agitating the fluid in the dispersion device at a measured agitation speed;
d) calculating the viscosity of the agitated fluid; and
e) controlling the viscosity at the particle-forming section by adjusting the agitation speed.
