What is Chezy’s Law?

The Chezy's equation is an empirical equation that describes the relationship between the velocity in a conduit and the channel geometry, slope, and a friction coefficient expressed as a Chezy's C.

Description about Chezy's Law

Even though Chézy’s law was originally intended for flow which is both steady (Unchanging in time) and uniform (unchanging along the waterway), they have been widely accepted as the governing friction equations in more generally unsteady and non-uniform flows.
