Encyclopedia
Antoine de Chézy was a French hydraulics engineer. He is known for the Chézy formula
, which concerned the velocity of pipe flow. He died in 1798 after being director of the École nationale des ponts et chaussées
for less than a year. His son was the orientalist Antoine-Léonard de Chézy.
Chézy formula
In fluid dynamics, the Chézy formula describes the mean flow velocity of steady, turbulent open channel flow:where*v is the mean velocity [m/s],*C is the Chézy coefficient [m½/s],*R is the hydraulic radius [m], and...
