Language:enStatus: Standard
Term: temperature factor of permeability
Synonym1:
Synonym2:
Synonym3:
Symbol: αF
Definition: quotient of the temperature coefficient of permeability by the permeability at temperature Θ

α F = α μ μ Θ = μ Θ μ ref μ Θ μ ref ( Θ Θ ref ) MathType@MTEF@5@5@+=feaagCart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHXgaruavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaiabeg7aHnaaBaaaleaacaqGgbaabeaakiabg2da9maalaaabaGaeqySde2aaSbaaSqaaiabeY7aTbqabaaakeaacqaH8oqBdaWgaaWcbaGaeqiUdehabeaaaaGccqGH9aqpdaWcaaqaaiabeY7aTnaaBaaaleaacqaH4oqCaeqaaOGaeyOeI0IaeqiVd02aaSbaaSqaaiaabkhacaqGLbGaaeOzaaqabaaakeaacqaH8oqBdaWgaaWcbaGaeqiUdehabeaakiabeY7aTnaaBaaaleaacaqGYbGaaeyzaiaabAgaaeqaaOWaaeWaaeaacqaH4oqCcqGHsislcqaH4oqCdaWgaaWcbaGaaeOCaiaabwgacaqGMbaabeaaaOGaayjkaiaawMcaaaaaaaa@5BB8@

or

α F = α μ μ ref = μ Θ μ ref μ ref 2 ( Θ Θ ref )

when Θ and ref differ insignificantly

NOTE – The temperature factor of permeability is a material property which enables to calculate the temperature coefficient of effective permeability αe by multiplying αF by e:

α μe = α F μ e MathType@MTEF@5@5@+=feaagCart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHXgaruavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaiabeg7aHnaaBaaaleaacqaH8oqBcaqGLbaabeaakiabg2da9iabeg7aHnaaBaaaleaacaqGgbaabeaakiabgwSixlabeY7aTnaaBaaaleaacaqGLbWaaWbaaWqabeaacqGHflY1aaaaleqaaaaa@44FC@
