Being able to calculate shear rate is useful because it will allow you to predict the behavior of a fluid more precisely. It also helps you make more informed decisions regarding the best type of channel to use in construction projects.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
