Assuming the laminar flow across the filter, the rate of filtration (dVf/dt) can be expressed as a function of pressure drop Dp by the modified D’Arcy’s equation as (where A is the area of filtering surface, K is the D’Arcy’s filter cake permeability and L is the thickness of the filter cake)

[A].

(1/A) dVf/dt = Δp/μ(L/K)
[B].
dVf/dt = (1/A)Δp/μ(L/K)
[C].
(1/A) dVf/dt = Δp/μ LK
[D].
dVf/dt = (1/A)Δp/μ LK
