Typical Porous Coeff for vehicule air filters
 

Hi,

Does anyone have any ball park figures for car air filters? I have a curve and calculated Internal resistance = 230 and Vicsous resistance as 66.

I got these by fitting a 2nd degree polynomial with Zero intercept to the curve supplied by the vendor which was in m/s(face velocity) vs Pa(pressure loss).

In a tutorial these values are 25 and 1500 respectively!

Cheers, Jess
