## Darcy-Weisbach Head Loss
Friction between the fluid and the pipe wall converts kinetic energy into heat, causing a pressure drop along the pipe.
### Formula
**h_f = f (L/D) (V^2 / 2g)**
where f is the Darcy friction factor (from Moody chart or Colebrook equation), L is pipe length, D is pipe diameter, V is flow velocity, and g is gravitational acceleration (9.81 m/s^2).

हल किया गया उदाहरण
Water at 2 m/s in a 100 mm pipe, 100 m long, with f = 0.02.
- D = 0.1 m
- V^2 / 2g = 4 / 19.62 = 0.2039 m
- h_f = 0.02 x (100/0.1) x 0.2039 = 0.02 x 1000 x 0.2039 = 4.08 m
- Pressure drop = 1000 x 9.81 x 4.08 / 1000 = 40.0 kPa
