## Darcy-Weisbach Pressure Drop
**h_f = f x (L / D) x (V squared / 2g)**
Where f is the Darcy friction factor, L is pipe length, D is diameter, V is velocity, and g is gravitational acceleration (32.174 ft/s squared). Multiply head loss in feet by 0.4333 to convert to psi.

हल किया गया उदाहरण
100 ft of 1-inch pipe carrying 10 GPM, friction factor 0.02.
- D = 1/12 = 0.0833 ft
- Area = pi x 0.04167 squared = 0.005454 sq ft
- V = (10/448.831) / 0.005454 = 4.09 ft/s
- h_f = 0.02 x (100/0.0833) x (4.09 squared / 64.348) = 6.24 ft
- Pressure drop = 6.24 x 0.4333 = 2.70 psi
