# Head Loss Calculator English Español

Darcy Weisbach relates the head loss (or) pressure loss due to friction along a given length of pipe to the average velocity of the fluid flow. Here we can calculate the head loss based on the friction factor, pipe length, pipe diameter, flow velocity and acceleration of gravity.

Head Loss: hL = (f * L * V2) / (2Dg) Friction Factor: f = (2hL * D * g) / (L * V2) Pipe Length: L = (2hL * D * g) / (f * V2) Pipe Diameter: D = (f * L * V2) / (2hL * g) Flow Velocity: V = √((2hL * D * g) / (f * L)) Acceleration of Gravity: g = (f * L * V2) / (2hL * D) Where, hL = Head Loss f = Friction Factor L = Pipe Length D = Pipe Diameter V = Flow Velocity g = Acceleration of Gravity
