set_diameter_from_interstitial_velocity(Q: float, u0: float) → None

Set diamter from flow rate and interstitial velocity.

In literature, often only the interstitial velocity is given. This method, the diameter / cross section area can be inferred from the flow rate, velocity, and bed porosity.

Parameters:

Qfloat

Volumetric flow rate.

u0float

Interstitial velocity.
