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.

1. Does a low flow rate mean a low shear rate or a high flow rate mean a high shear rate?
Not always! Download the application note and on page 3, we explain why!
2. Can RheoSense viscometers thixotropic materials?
Yes! VROC technology can handle thixotropic samples.
