kartikeya parmar


I have calculated resistance coefficients based on the manual formula and it comes out to be K=4.87×10^(-7) and C2=480.10. But the only thing i am not able to understand that in paper says calculation for different darcy number like 0.1,0.01,0.001. how i change the K value as K value i have calculated using K=(d^2xphi^3)/(150x(1-0.9)^2).


Also if i take K=4.87×10^(-7) viscous resistance is very high and then if i change Richarson number i see no difference in plot.

please help

Just tell me how to change Darcy number as paper says for different darcy number
