Effluent water is flowing in a near-level 1.5 m-wide concrete sluiceway at 0.65 m/s and a depth of 2.2 m upstream of a sluice gate. The sluice gate is opened 0.25 m above the channel invert. (a) Compute the specific energy of the flow approaching the sluice gate. (b) Assuming negligible losses across the sluice gate, what is the flow velocity if the flow depth downstream of the sluice gate is 0.229 m? (c) Compute the Froude number for the flow immediately downstream of the sluice gate. What is the flow condition?
