For each gradually varied flow transition, you must know both boundary conditions and you must also calculate length of that transition. In order to use this technique, it is important to note you must have some understanding of the system you are modeling. The resulting energy equation is shown below: See Pressure head for more details.) In open channels, it is assumed that changes in atmospheric pressure are negligible, therefore the “pressure head” term used in Bernoulli’s Equation is eliminated. (Note, energy and head are synonymous in Fluid Dynamics. The energy equation used for open channel flow computations is a simplification of the Bernoulli Equation (See Bernoulli Principle), which takes into account pressure head, elevation head, and velocity head. ![]() ![]() Note the location of critical flow, subcritical flow, and supercritical flow. A diagram showing the relationship for flow depth (y) and total Energy (E) for a given flow (Q).
