WebMar 30, 2024 · The head loss in a fluid system is typically calculated using the Darcy-Weisbach equation, which relates the head loss to the fluid's velocity, the pipe's diameter and the friction factor. The Darcy-Weisbach equation is expressed thusly: hL = f (L/D) (V^2/2g) Where: "hL" is the head loss. "f" is the friction factor "L" is the length of the pipe.
