Deriving an expression using Bernoullis equation.

[Tianman]

Hi!

This is my first post, so i apologise if i leave out any information.

I need to derive an expression for the theoretical velocity of flow in an open channel using the Bernoulli Equation.

I realize it is probably a simple question but i am sort of a beginner. Any help appreciated, thanks!

Bernoulli's Equation itself it derived from the conservation of energy. Having said that, what could be said about potential and kinetic energies at the two locations of concern?

p.s. I'm assuming you don't need a velocity distribution which Bernoullis won't get you.
