Could someone explain me what is the Gurley method to determine the airflow through a material & give the relationship w/ the airflow in ml/(min.mm².mbar) ?
thx
Im not clever enough.....can someone help me ?
I got a circular membrane ( small diameter, lets name it D ; material :ePTFE ) fixed on his edge.
Who can I know the cut frequencies of the system and the frequency band which will be able to go trough this filter ?
