DOI: 10.1615/AtoZ.d.darcy_number

There are two dimensionless groups given the name Darey number.

where Δp is the pressure drop, D the diameter, ρ fluid density, u fluid velocity, and L the length over which the pressure drop is measured. f is the Fanning friction factor (see Friction Factors).

where D' is the permeability coefficient of a porous medium with units m2/s (see Darcy's Law).
