Frequently Asked Questions
-
What does square foot per second measure?
-
It measures kinematic viscosity in the US customary system, representing the ratio of dynamic viscosity to density for fluid flow behavior.
-
When is petastokes conversion useful?
-
Petastokes conversions are mainly applicable in geophysical or planetary science scenarios involving extremely large-scale viscosity values.
-
Can I use petastokes in everyday engineering calculations?
-
No, petastokes are rarely used in standard engineering practice due to their immense scale and are mostly for academic or scaling exercises.
Key Terminology
-
Square foot per second (ft²/s)
-
An imperial unit of kinematic viscosity measuring area per unit time, representing fluid momentum diffusion.
-
Petastokes (PSt)
-
A kinematic viscosity unit equal to 10¹⁵ stokes, used mainly for very large-scale or theoretical viscosity values.
