Darcy-Weisbach Equations for Hydraulics Fluid Mechanics
In fluid dynamics, the Darcy–Weisbach equation is an empirical equation that relates the head loss or pressure loss due to friction along a given length of pipe to the average velocity of the fluid flow for an incompressible fluid. The equation is named after Henry Darcy and Julius Weisbach.

Darcy-Weisbach equations are used to calculate the major pressure or head loss due to friction in pipes, ducts, or tubes.

Formula:
h = fLv²/2Dg

Where:
h - is the head loss
f - is the friction factor
L - is the pipe length
D - is the pipe diameter
v - is the flow velocity
g - is the acceleration of gravity

### 2/5 — Little value. Wasted money

*2020-08-15*

I’d has no function to calculate the friction factor which is the most tedious part of the equation. It has to be entered manually.
