Tips & Best Practices
-
Ensure that permeability values are measured consistently at 23°C for accurate conversion.
-
Use this conversion to integrate permeability data with hydraulic conductivity modeling effectively.
-
Consider permeability’s temperature dependency when applying converted values in varied conditions.
-
Pair conversion results with relevant fluid properties such as viscosity for precise flow analyses.
Limitations
-
Permeability values depend on the 23°C reference and vary with temperature changes.
-
This conversion factor is very small, reflecting different physical aspects between permeability and flow resistance.
-
Additional parameters like fluid viscosity are needed for exact modeling of transport phenomena.
-
Converted results represent inverse hydraulic conductivity and do not directly quantify gas or vapor transmission.
Frequently Asked Questions
-
What does permeability (23°C) measure?
-
Permeability (23°C) quantifies a material's intrinsic ability to allow gas or vapor transmission at the reference temperature of 23°C, independent of sample thickness.
-
Why convert permeability to kilogram/pascal/second/square meter?
-
Converting to kilogram/pascal/second/square meter relates permeability to flow resistance or hydraulic conductivity inverses, aiding interdisciplinary analyses in porous media and membrane systems.
-
Can this conversion be used for different temperatures?
-
No, this conversion assumes permeability measured specifically at 23°C; values at other temperatures require separate consideration due to temperature dependence.
Key Terminology
-
Permeability (23°C)
-
A permeability coefficient of a material measured at 23°C, describing the intrinsic ability to transmit gas or vapor per unit pressure difference.
-
Kilogram/pascal/second/square meter
-
An SI-derived unit expressing permeability-related flow resistance or inverse hydraulic conductivity in porous media.
-
Hydraulic Conductivity
-
A measure of a material’s capacity to allow fluid flow under pressure, often inversely related to flow resistance.
