Frequently Asked Questions
-
What does nanostokes measure?
-
Nanostokes measure kinematic viscosity, indicating a fluid's resistance to flow under gravity, especially for very low-viscosity fluids.
-
Why convert nanostokes to square millimeter per second?
-
Converting to square millimeter per second provides a more common and industry-standard unit to compare fluid viscosities in engineering and laboratory settings.
-
Are nanostokes used for all viscosity measurements?
-
No, nanostokes are primarily used for very low viscosity fluids such as those in microfluidics and specific thin-film lubrication applications.
