Some questions about hydraulic conductivity

[Devin-one]

Dear Professor, I have some questions about hydraulic conductivity to ask you.
Firstly, the hydraulic conductivity of the throat can be obtained by the Hagen-Poiseuille equation. How can I draw the curve of it?
Secondly, if I want to calculate the porosity distribution like the throat hydraulic conductivity distribution, how would I do it ?
Finally, is hydraulic conductivity equial to permeability coefficient in OpenPNM?

Firstly, the hydraulic conductivity of the throat can be obtained by the Hagen-Poiseuille equation. How can I draw the curve of it?

Do you mean how can you plot the distribution of hydraulic conductance? If so, just use matplotlib's hist

import matplotlib.pyplot as plt
plt.hist(phase["throat.hydraulic_conductance"])

Secondly, if I want to calculate the porosity distribution like the throat hydraulic conductivity distribution, how would I do it ?

What exactly do you mean by "porosity distribution"?

Finally, is hydraulic conductivity equal to permeability coefficient in OpenPNM?

I don't know the exact definition of "permeability coefficient", so I'll explain in terms of just permeability (k), as defined by:

In openpnm, we refer to (k/nu/L) as "hydraulic conductance".
