- The flow rate of water in a 5-m-wide horizontal open channel is being measured with a 0.60-m-high sharp-crested rectangular weir of equal width. If the water depth upstream is 1.5 m, determine the flow rate of water.What length of a Cipolletti weir should be constructed in order that the head of flow will be 0.96m when the flow rate is 3.76 m3/s?A full-width sharp-crested weir is to be used to measure the flow rate of water in a 7-ft-wide rectangular channel. The maximum flow rate through the channel is 180 ft3/s, and the flow depth upstream from the weir is not to exceed 3 ft. Determine the appropriate height of the weir.
- A rectangular, sharp crested weir width is 1.5m long, How high should the weir be placed in a channel to maintain an upstream depth of 1.95m for a flow of 0.30 cum/sec? use Francis FormulaA rectangular contracted weir 3m long is built in the left end of a rectangular channel 6m wide. How high is the weir if the depth of water upstream is 1m when the discharge is 1.15 m3/s. Neglect velocity of approach and use weir factor =1.65.Water flows over a 1.5-m-high sharp-crested rectangular weir. The flow depth upstream of the weir is 2.5 m, and water is discharged from the weir into an unfinishedconcrete channel of equal width where uniform-flow conditions are established. If no hydraulic jump is to occur in the downstream flow, determine the maximum slope of the downstream channel.
- A weir is used to measure the flowrate in an open channel that is (Bw =) 5 m wide and (Ho =) 2 m deep. The depth of water over the crest of the weir (H) should be no less than 0.5 m when the flowrate (Q) is 1 m3/s and the water level should be at least 30 cm below the top of the channel. Determine the crest length of the weir (B).What is the discharge capacity of an irrigation channel having a total depth of 1.5 meter (including freeboard) , bottom width 1.2 m, side slope 2:1, and a hydraulic gradient of 0.001 m/m? Assume n=0.04 and freeboard to be 20% of the flow depth.A weir installed at the end of a rectangular channel controls the flow of water. The rate of flow is 0.62 m^3/s. If the error in measuring the head is 0.018m, determine the percentage error in the measured flow if a 90 degree V-notch weir is used.
- Calculate the flow rate through a perpendicular V-notch weir having a head of 1.75' over it. Assume the value of Cd equal to 0.67.In a 3.0 m wide open rectangular channel, the flow rate is (1158) lt/sec flows. The depth of the channel is 2.9 m. At a downstream section, there is constriction with a width of 2.50 m and a 0.20 m bump on the bottom. Calculate the water depths of both upstream and downstream.A rectangular, sharp-crested weir with end contractions is 1.4 m long. How high should itbe placed in a channel to maintain an upstream depth of 2.35 m for 0.40 m³/s flow
