Hi.

I need help to find out the inertial resistance and viscous resistance.

I'm using the below formulaes to calculate it.

RV = [ 150 (1-e)^2 ] / [ (sphericity)^2 * (Hydraulic dia)^2 * (porosity)^3 ]
RI = [ 3.5 (1-e) ] / [ (sphericity) * (Hydraulic dia) * (porosity)^3 ]

I have attached the dimensions in the image. Dimensions are 2.83*.08*49 mm

How to find hydraulic dia and sphericity ??

Thanks in advance.
