Chezy Formula

The Chézy formula is an semi-empirical resistance equation which estimates mean flow velocity in open channel conduits. The relationship was realized and developed in 1768 by French physicist and engineer Antoine de Chézy (1718–1798) while designing Paris's water canal system. Chézy discovered a … See more The Chézy formula describes mean flow velocity in turbulent open channel flow and is used broadly in fields related to fluid mechanics and fluid dynamics. Open channels refer to any open conduit, such as rivers, ditches, … See more The relationship between linear momentum and deformable fluid bodies is well explored elsewhere in Wikipedia, as are Navier–Stokes equations for incompressible … See more Both formulas are widely taught and used in modern times. As both equations reference a single control volume location along the channel, neither address friction factor or head loss directly, but change in pressure head may be calculated by combining them … See more • Hydrology • Hydraulic engineering See more Once this relationship was established by Chézy, many engineers and physicists (see the below section Authors of flow formulas) continued to search for ways to improve Chézy's … See more • Albert Brahms (1692–1758) • Antoine de Chézy (1718–1798) • Claude-Louis Navier (1785–1836) • Adhémar Jean Claude Barré de Saint-Venant (1797–1886) See more • History of the Chézy Formula See more WebNov 23, 2011 · The Chezy equation applied to pipes with turbulent flow is.
