(Figure 8) The value of y 2 /y 1 is a ratio of depths that represent a dimensionless jump height; for example, if y 2 /y 1 = 2, then the jump doubles the depth of flow. As the upstream Froude Number increases (moves toward more supercritical flow), the ratio of the downstream depth to the upstream depth also increases, and the graph verifies ...
As the free-flow coefficient (K) and the free-flow exponent (n) depend only upon flume length, intermediate sizes Cutthroat flumes can be developed without the need for laboratory verification. The flat-bottomed design means that the flume can be retrofitted into existing channels without the need to raise the flume or adjust the downstream ...
Only the upstream depth needs to be measured to calculate the flow rate. A free flow also induces a hydraulic jump downstream of the flume. Submerged flow occurs when the water surface downstream of the flume is high enough to restrict flow through a flume, submerged flume conditions exist. A backwater buildup effect occurs in a submerged flume.
Only the single depth (primary point of measurement - Ha) needs to be measured to calculate the flow rate. A free flow also induces a hydraulic jump downstream of the flume. Submerged Flow – when the water surface downstream of the flume is high enough to restrict flow through a flume, the flume is deemed to be submerged.
The HEC-RAS model calculated that the water backs up to a height of 9.21 meters at the upstream side of the sluice gate, which is the same as the manually calculated value. Normal depth was achieved at approximately 1,700 meters upstream of the gate. HEC-RAS modeled the hydraulic jump to occur 18 meters downstream of the sluice gate.
In order to form a watertight unit, a packaged metering manhole is provided with a solid fiberglass base at the bottom of the manhole barrel. The base can serve not only as the bottom of the manhole, but also as a means of anchoring the manhole to a concrete slab (required to counteract the buoyant forces on the manhole).
Select values of upstream meter tube length, and flow conditioner location, to be used for the performance evaluation. Install the flow conditioner at the desired location. First, perform a test for either the two 90° elbows out-of-plane installation, or the high swirl installation for β {\displaystyle \beta } = 0.40 and for β {\displaystyle ...
The cone meter is a generic yet robust differential pressure (DP) meter that has shown to be resistant to effects of asymmetric and swirling flow. While working with the same basic principles as Venturi and orifice type DP meters, cone meters don't require the same upstream and downstream piping. [9]
