The Darcy friction factor is crucial in fluid dynamics, as it quantifies the resistance or friction in a pipe. It is used in the Darcy-Weisbach equation for determining pressure drops in a pipe due to frictional forces.
Darcy Friction Factor Formula
- For laminar flow (Re < 2000):
\[ f = \frac{64}{Re} \] - For turbulent flow (Re > 4000):
The Colebrook-White equation is applied:
\[ \frac{1}{\sqrt{f}} = -2 \log_{10} \left(\frac{\epsilon/D}{3.7} + \frac{2.51}{Re \cdot \sqrt{f}}\right) \]
This calculator is particularly useful in civil, chemical, and mechanical engineering fields for designing efficient piping systems.
