WebMar 5, 2024 · In a uniform open-channel flow, for which both kinetic energy and potential energy are the same at every cross section but potential energy decreases downstream, the head loss is simply the rate of decrease of elevation head downstream, or in other … WebDefinition. Uniform equilibrium open channel flows are characterized by a constant depth and constant mean flow velocity: ∂ d ∂ s = 0 and ∂ v ∂ s = 0. where s is the co-ordinate in the flow direction. Uniform equilibrium open channel flows are commonly called ‘uniform flows’ or ‘normal flows’.
