Darcy Weisbach - Head Loss Formula - Fluid Mechanics

Formula

Formula:

Head Loss:
h_L = (f * L * V²) / (2Dg)

Friction Factor:
f = (2h_L * D * g) / (L * V²)

Pipe Length:
L = (2h_L * D * g) / (f * V²)

Pipe Diameter:
D = (f * L * V²) / (2h_L * g)

Flow Velocity:
V = √((2h_L * D * g) / (f * L))

Acceleration of Gravity:
g = (f * L * V²) / (2h_L * D)

Where,
h_L = Head Loss
f = Friction Factor
L = Pipe Length
D = Pipe Diameter
V = Flow Velocity
g = Acceleration of Gravity
