Frequently Asked Questions
-
What does kilogram/pascal/second/square meter measure?
-
It is a unit representing flow resistance per unit length in porous media, relating to inverse hydraulic conductivity.
-
Why use permeability (23°C) as a unit?
-
Permeability (23°C) provides a standardized measure of a material's ability to transmit gases or vapors at room temperature, allowing comparison independent of sample thickness.
-
Can I use this converter for temperatures other than 23°C?
-
No, permeability values are temperature-dependent and accurate only at or near 23°C.
Key Terminology
-
Kilogram/pascal/second/square meter
-
An SI-derived unit representing flow resistance per unit length in porous media, algebraically equivalent to seconds per meter.
-
Permeability (23°C)
-
A permeability coefficient measured at 23°C representing a material's intrinsic ability to transmit gases or vapors independent of sample thickness.
-
Hydraulic Conductivity
-
The ability of porous media to transmit fluid, inverse to flow resistance measured in kilogram per pascal second square meter.
