Understanding Pressure Drop

Pressure drop, or head loss, occurs in a pipe because of friction between the fluid and the pipe wall. The Darcy-Weisbach equation is a fundamental formula used to calculate this loss.

Darcy-Weisbach Equation

ΔP = f * (L/D) * (ρ * v²/2)

ΔP = Pressure Drop
f = Darcy Friction Factor (dimensionless)
L = Pipe Length
D = Pipe Diameter
ρ = Fluid Density (assumed water)
v = Flow Velocity

This calculator simplifies the process by working directly with flow rate.
