WebDec 6, 2009 · Darcy’s Law Equation The equation for Darcy’s Law is based on the observations that the flow rate through a porous medium (such as an aquifer) is proportional to the cross-sectional area perpendicular to flow and is also proportional to the head loss per unit length in the direction of flow. WebMar 28, 2024 · The Darcy Weisbach equation is used to determine the pressure drop across a pipe for a fluid. Mathematically this is: ΔP = (f × L × V² × ρ) / (2 × D) where P is pressure, f is friction factor, L is pipe length, V is flow velocity, D is pipe diameter, and ρ is the fluid density. How do I find pressure drop?
