What is Shear Rate?
Shear rate is the velocity gradient in a fluid and indicates how strongly layers of fluid move relative to each other.
View High Speed AgitatorsShear Rate Explained
Shear rate is the velocity gradient in a fluid and indicates how strongly layers of fluid move relative to each other. In industrial mixing, this parameter should be reviewed along with tank geometry, impeller type, fluid properties and operating objective.
Common Applications
- Polymer mixing
- Cell culture
- Floc handling
- Emulsion preparation
Important For
- High shear can damage polymer, cells and flocs
Selection Factors
Correct selection depends on the process objective and site conditions. For Shear Rate, Premix usually reviews these points before recommending equipment:
- Tip speed
- Impeller type
- Gap clearance
- Fluid viscosity
Why It Matters In Plant Operation
Shear Rate affects process stability, chemical usage, equipment life and final output quality. A correctly selected solution helps reduce trial-and-error at site and supports more predictable daily operation.
