Sir, what are the porous materials that can be used for better detection of an ethanol gas or vapour? Will permittivity has its effect on permeability and porosity of a material during detection?
Yes, this is what is presented in the video. Empirically the permeability scales as the square of a typical throat radius. You can also use the Kozeny-Carmen equation to relate permeability to porosity and a typical pore size.
@@BoffyBlunt Sir I have only pore size of a porous plate and I want to calculate the permeability of it. Kozney-Carmen and other relations require porosity as well.
Thanks

I am not an expert here: for gas analysis, you would need to sorb the gas to the porous medium for analysis.
@@BoffyBlunt ok Sir, thank you
Sir, Is there any relation/equation to calculate porosity and permeability from pore size?
Yes, this is what is presented in the video. Empirically the permeability scales as the square of a typical throat radius. You can also use the Kozeny-Carmen equation to relate permeability to porosity and a typical pore size.

@@zainrasheed1760 Yes you do need to know both pore size and porosity to estimate permeability.
What is the permeability of porous glass?
It depends - as described in the video - on the pore size.
Got it. Thank you sir👍
