Specific Surface - Air Permeability Calculator
Posted by Dinesh onOnline filtration calculator helps to calculate the air permeability specific surface of a powder material. The air permeability specific surface of a powder material is a single-parameter measurement of the fineness of the powder. It is usually expressed in m²•kg-1 ("mass specific surface") or m²•m-3 ("volume specific surface").
Air Permeability Specific Surface of a Powder Material Calculation
Formula:
where:
d is the cylinder diameter
ρ is the sample particle density
ε is the volume porosity of the bed
δP is the pressure drop across the bed
l is the cylinder length
η is the air dynamic viscosity
Q is the flowrate
S is specific surface
