Water approaches a sharp-crested rectangular weir through a channel that is 2 m wide. The depth of flow in the channel is 1 m. The weir crest is 0.6 m above the base of the channel and has a crest width of 0.8 m. It is located in the centre of the channel. Assuming a coefficient of discharge of 0.61, and ignoring side contractions, determine the discharge over the weir: a) Assuming the approach velocity is zero b) Including the...

A rectangular suppressed weir, 1 m in length is used in a reservoir with an area of 50 square yards. During dry season, it was requested for 40 cubic meters per second of water to be discharged using the weir. If the discharge coefficient is 0.72 and the initial head of the weir was 1.20 m, answer the following: a, What will be the final head acting on the weir after the said volume was discharged? b. How long will...

A vertical sluice gate in a long rectangular channel 5 m wide is lowered to produce an opening of 1.0 m. Assuming that the free flow conditions exist at the vena contracta downstream of the gate verify that the flow in the vena contracta is supercritical when the discharge is 15 m3/s and determine the depth just upstream of the gate, Cv = 0.98; Cc = 0.6. Take the upstream velocity energy coefficient to be 1 and that at the...

Question 2 (1 point) This swing gate is used to hold back water in a channel. The channel is 1 m wide, and the water is h = 0.9 metres deep. The swing gate sits at an angle of θ = 25 degrees, as depicted. The gate could be supported entirely by a force and moment on the pin at the bottom, or by other reaction forces at mountings not shown in this diagram. Neglecting the weight of the gate,...
