singulière perte de pression conduits tuyaux

Overview

Minor pressure losses occur at pipe fittings, valves, bends, tees, expansions, and contractions. Although called 'minor', these losses can be significant in short piping systems.

Variables

Symbol	Description	Unit
$K$	Minor loss coefficient	—
$\Delta P$	Pressure drop	Pa
$L_{eq}$	Equivalent pipe length	m

Formula

$\Delta P = K \cdot \frac{\rho v^2}{2}$
