Conversion does not account for temperature or pressure effects impacting viscosity.
-
Only applicable to kinematic viscosity, not dynamic viscosity or other properties.
-
Pay attention to differences in time units to avoid data misinterpretation.
Frequently Asked Questions
-
What does square foot per hour measure?
-
Square foot per hour is a unit of kinematic viscosity representing the rate of momentum diffusion in a fluid, expressed as area per time in imperial units.
-
Why convert from square foot/hour to square inch/second?
-
Conversion is necessary to align viscosity data from hourly to per-second time scales and to use granular units preferred in detailed fluid flow analyses and certain engineering applications.
-
Can this conversion be used for dynamic viscosity?
-
No, this conversion strictly applies to kinematic viscosity and should not be used for dynamic viscosity or other fluid properties.
