If the flow properties, say the depth of. flow, in an open channel remain constant along. the length of channel, the flow is said to be. uniform. As a corollary of this, a flow in which. the flow properties vary along the channel is. termed as non-uniform flow or varied flow. birmingham business license taxWebMar 5, 2024 · Differentiate Equation 5.5.1 with respect to the flow direction x: (5.7.2) d E w d x = d ( U 2 / 2 g) d x + d y d x + d h o d x. The term on the left side of Equation 5.7.2 is the rate of change in total energy in the downstream direction.
