How does open-channel flow differ from internal flow?
Water is to be transported in a finished-concrete rectangular channel with a bottom width of 1.2 m at a rate of 5 m3 /s. The channel bottom drops 1 m per 500 m length. The minimum height of the channel under uniform-flowconditions is(a) 1.9 m (b) 1.5 m (c) 1.2 m (d) 0.92 m (e) 0.60 m
A sluice gate with free outflow is used to control the discharge rate of water through a channel. Determine the flow rate per unit width when the gate is raised to yield a gap of 50 cm and the upstream flow depth is measured to be 2.8 m . Also determine the flow depth and the velocity downstream
