characteristics of uniform flow in open channel
Answer (1)
26th Nov, 2020
Hello there,
Open-channel flows are those that are not entirely included within rigid boundaries; a part of the flow is in contract with nothing at all, just empty space.
Steady flow in a channel can be either Uniform or Non-uniform (varied).When the average velocities in successive cross sections of a channel are the same, the flow is uniform. This occurs only when the cross section is constant. Non-uniform flow results from gradual or sudden changes in the cross sectional area.
Characteristics of uniform flow in open channel are as follows:
- Open channel flow is characterized by a flow not completely enclosed by solid boundaries
- Free surface is subject to atmospheric pressure
- Flow is not caused by external head but by the gravity component along the slope of the channel
I hope it helps.
