Frequently Asked Questions
-
What does decistokes measure?
-
Decistokes measures kinematic viscosity, representing the ratio of a fluid's dynamic viscosity to its density, expressed in CGS units.
-
Why convert decistokes to square foot/hour?
-
Conversion facilitates comparing or reporting viscosity values in imperial units common in U.S.-based engineering and industrial applications.
-
Can this conversion be used for non-steady fluids?
-
No, this conversion assumes steady-state fluid properties and may require adjustments for changing temperature or pressure conditions.
Key Terminology
