The Peripheral overflow weir of a settling tank has 60 identical 90 degree V notch weirs, all set in the same apex level.if the daily flow rate is 1296m3 fine the flow over an individual V notch in L/s
Problem 4: Find the discharge in a 80 degrees triangular weir with a head of 1.8 ft over the weir. The discharge coefficient is 0.62.
Solve it quickly
A contracted from the two ends sharp-crested weir is installed in a channel and has a crest heigh of 7.2 m and a crest effective length of 4 m. The discharge coefficient (Cd) is 1.81. At design flow, a 1.1 m static head develops upstream of the weir. Determine the crest height of a non- contracted-90°-V-notch (replacement) weir with Cd =2 that would discharge the same design flow rate without raising the upstream flow depth in the channel. Y
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
A contracted weir which is built in a rectangular channel has a length of weir of 1.407 m and a height above the crest of 0.20 m. Using Francis formula, determine the discharge flowing in the weir if it has two end contractions in cum/sec.
Water in a 20-ft-wide rectangular channel, flowing at120 ft3/s and a depth of 10 ft, is to be metered by arectangular weir with side contractions, as in Table 10.2b.Suggest some appropriate design values of b, Y, and H tomatch the table conditions for this weir.
Determine the required length of a contracted weir similar to that shown in Fig. 14.17(b) to pass 15 ft³/s of water. The height of the crest is to be 3 ft from the channel bottom, and the maximum head above the crest is to be 18 in.
A sharp-crested suppressed rectangular weir 1m long and a standard 90- degree V-notch weir are placed in the same weir box with the vertex of the V- notch weir 150mm below the crest of the rectangular weir. Determine the head on the rectangular weir. Determine the head on the rectangular weir when their discharges are equal. Use Francis Formula.
