8.4 Dimensional Analysis of Pipe<strong>Flow</strong>• Most turbulent pipe flow analyses are based on experimentaldata and semi-empirical formulas.h L =h Lmajor +h Lm<strong>in</strong>or• Major losses : loss associated with the straight portion of thepipe Δ p=F( V, D, l,ε, μ,ρ)• pressure drop and head loss <strong>in</strong> a pipe• For lam<strong>in</strong>ar flow the pressure drop isfound to be <strong>in</strong>dependent of theroughness of the pipe.• For turbulent flow, the pressuredrop is expected to be a functionof the roughness.
