  3. 3

    See ΔP + head loss

    Darcy-Weisbach friction calculation.

Frequently Asked Questions

Darcy-Weisbach equation?
ΔP = f × (L/D) × (ρV²/2). Where f = friction factor, L = length, D = diameter, ρ = density, V = velocity. f comes from Moody diagram (Reynolds + roughness).
Common roughness values (mm)?
Smooth (PVC, drawn copper): 0.0015. Commercial steel: 0.045. Galvanized iron: 0.15. Concrete: 0.3-3.0. Old cast iron: 0.5+.
When does this fail?
Two-phase flow, compressible gas at high velocity (>0.3 Mach), non-Newtonian fluids. For those, use specialized models. Single-phase liquid + low gas: D-W is solid.
