Calculating Shear Rate: Easy-Peasy

In technical information, application notes

A frequently asked question is, "what shear rates should I be using for my measurements?"

Shear rates are the foundation of performing viscosity experiments. Viscometers determine viscosity by dividing shear stress experienced by the fluid by the shear rate. When developing novel fluids, their viscosity must be measured to characterize the fluid behavior for multiple environments. 

During the development and manufacturing process, fluids will experience different shear rates, which may also differ from the shear rates they experience in the hands of end users. So, knowing how to calculate shear rate is critical to performing experiments that will predict fluid viscosity outside the lab environment.
