Friction turns pressure into heat as fluid moves through a pipe. Head loss h_f = f·(L/D)·v²/2g, where the friction factor f depends on the Reynolds number and pipe roughness. Educational tool.

Velocity1.27 m/s

Reynolds number1.27e+5

Friction factor f0.0196

Head loss0.81 m

Pressure drop7.9 kPa

Governing equation

h_{f} = f \frac{L}{D} \frac{v ^{2}}{2 g} = 0.020 \cdot \frac{50}{0.10} \cdot \frac{1.2 7 ^{2}}{2 \cdot 9.81} = 0.81 m, R e = \frac{ρ v D}{μ} = 1.3 e + 5

Reading this result: Fully turbulent in a relatively smooth pipe: friction factor depends weakly on Reynolds number, and head loss grows roughly with the square of flow rate.
