fp＝150/Grp＋1.7555
where fp and Grp are defined as
fp＝(Δp/L)·[Dp/(ρ·Vs²)]·[ε³/(1－ε )] and Grp＝(Dp·Vs·ρ)/[(1－ε)·μ]
where,
Δp is the pressure drop across the bed,
L is the length of the bed (not the column),
Dp is the equivalent spherical diameter of the packing,
ρ is the density of fluid,
μ is the dynamic viscosity of the fluid,
Vs is the superficial velocity (i.e. the velocity that the fluid would have through the empty tube at the same volumetric flow rate), and
ε is the void fraction of the bed (Bed porosity at any time).
