What is Reynolds number?

Re = vD/ν. It determines flow regime: 4000=turbulent.

How is head loss calculated?

Darcy-Weisbach: hf = f(L/D)(v²/2g), where f is friction factor.

Reynolds number and pipe roughness. Use Swamee-Jain for turbulent flow.

Hitung laju aliran volumetrik, kecepatan, dan bilangan Reynolds dalam pipa.

v = \frac{Q}{A}, Re = \frac{v D}{ν}, h_{f} = f \frac{L}{D} \frac{v ^{2}}{2 g}
