Cake resistance formula

WebIt is logical to assume that the resistance of the cake is proportional to its thickness L. The proportionality constant r (m −2) is called ‘specific cake resistance’. The resistance of the filter medium may be seen as the resistance of an additional fictitious cake thickness, L f. Substituting in Eq. (8.3), we obtain: WebR = Resistance. α = Specific cake resistance. s= Compressibility factor. Filter media: The filter medium acts as a mechanical support for the filter cake and it is responsible for the …
