Frequently Asked Questions
-
What does square foot per second measure in viscosity?
-
Square foot per second (ft²/s) is an Imperial unit of kinematic viscosity measuring how quickly momentum spreads through a fluid, defined as dynamic viscosity divided by density.
-
Why convert from square foot/second to centistokes?
-
Conversion enables aligning US customary measurements with the internationally recognized centistokes unit, facilitating comparison and consistency in engineering and lubrication data.
-
What industries use these viscosity units?
-
Automotive lubricant formulation, hydraulic fluid specification, mechanical engineering, and fluid mechanics research commonly use these units.
-
Does temperature affect kinematic viscosity conversion?
-
Yes, viscosity values depend on temperature, so conversions should use values specified at the same temperature to remain valid.
Key Terminology
-
Square foot per second (ft²/s)
-
An Imperial unit of kinematic viscosity representing a fluid's dynamic viscosity divided by its density, expressing momentum diffusion rate.
-
Centistokes (cSt)
-
A metric unit of kinematic viscosity equal to one hundredth of a stoke, commonly used to describe lubricant and fluid flow resistance.
-
Kinematic viscosity
-
The ratio of dynamic viscosity to fluid density, indicating how a fluid resists flow under gravity.
