Lactose particle properties were to be studied based on modification of equipment parameters on the L1A Fitz mill by assessing particle size distribution.

Jet propulsion is produced by some reaction engines or animals when thrust is generated by a fast moving jet of fluid in accordance with Newton's laws of motion.It is most effective when the Reynolds number is high—that is, the object being propelled is relatively large and passing through a low-viscosity medium.. In biology, the most efficient jets are pulsed, rather than continuous, at ...
