Pressure Drop (Darcy-Weisbach)

Determine frictional pressure loss in your fluid delivery lines.

Friction Factor (f)

Pipe Length (L) m

Pipe Diameter (D) m

Fluid Density (ρ) kg/m³

Velocity (v) m/s

Pressure Drop (ΔP)

0.00 Pa

ΔP = f * (L / D) * (ρ * v² / 2)

Fluid System Design

Correctly calculating pressure drop is the difference between a system that flows and one that cavitates. Ensure your pump selection accounts for these losses plus any minor losses from fittings, bends, and valves.
