The chemical engineering design handbook contains formulas from Diehl-Koppany for calculating the critical point, where ‘de’ represents the equivalent diameter of the packing channel. How is this value calculated? Is it the hydraulic diameter?

The definition of hydraulic diameter is: 4 * porosity / specific surface area. As for the equivalent diameter, I’m not sure whether it refers to the inner diameter of the tower; I’m not a designer, so I’m not entirely clear on this

The hydrodynamics of plate corrugated fillers is ideally calculated using Chinese PCPC.

Is there a result for this? I'm confused
