What to enter
| Input | Meaning and units |
|---|---|
| Shear stress (Pa) | Enter shear stress in Pa; use the same basis as the other measurements. |
| Shear rate (1/s) | Enter shear rate in 1/s; use the same basis as the other measurements. |
Understanding your result
Read Dynamic viscosity (Pa·s) in the units and model stated on this page. The formula mu=stress/rate defines the relationship; measurement accuracy and model applicability are separate from numerical precision.
Common mistakes
- Mixing input units or changing the physical meaning of a variable without changing the model.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.
