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. |
