What is Sequent depth ratio?
The sequent depth ratio is one of the important characteristics of hydraulic jump useful in designing the stilling basin. By increasing bed slope, the sequent depth ratios show increasing trend in the range 3%–45%.
What is Sequent depth in open channel flow?
Conjugate, or sequent, depths are the paired depths that result upstream and downstream of a hydraulic jump, with the upstream flow being supercritical and downstream flow being subcritical.
What is the difference between alternate depths and Sequent depths?
These two depths are known as alternate depths. Conjugate depths: The two depths corresponding to the depth of flow, before and after of hydraulic jump having same momentum flux are termed as conjugate depths. Sequent depths are the same as conjugate depth.
How do you find critical depth?
The critical depth for a rectangular channel can be calculated from the fact that the Froude number is equal to one at critical flow conditions. For a rectangular channel , this fact leads to the equation: Vc/(gyc)1/2 = 1, where the subscript c is used to indicate critical flow conditions for the velocity and depth.
What is alternate depth?
Alternate depths are defined as the depths of flow in open channels for which the specific energy is the same. The generalized solution/equation yields both alternate depths from the known value of the non-dimensional specific energy.
What is Sequent depth ratio in hydraulic jump?
The sequent depth ratio of a hydraulic jump in a rectangular horizontal channel is 10.30.
What is N in Manning’s equation?
The Manning’s n is a coefficient which represents the roughness or friction applied to the flow by the channel. Manning’s n-values are often selected from tables, but can be back calculated from field measurements.
How do you calculate alternate depth?
The depths of flow can be either PR = y1 or PR` = y`1. These two possible depths having the same specific energy are known as alternate depths.
What is the alternate depth?
What are sequent depth and conjugate depth?
This means that the flow depth on either side of the jump will have the same momentum, and in this way, if the momentum and flow depth on either side of the jump is known, it is possible to determine the depth on the other side of the jump. These paired depths are known as sequent depths, or conjugate depths.
What is the sequent depth ratio of hydraulic jump?
The sequent depth ratio is one of the important characteristics of hydraulic jump useful in designing the stilling basin. Despite its importance, the exact value of sequent depth ratio is still undetermined.
Does sequent depth ratio depend on roughness heights and slope?
Despite its importance, the exact value of sequent depth ratio is still undetermined. In the present study an attempt has been made to find out the effects of roughness heights and slopes by conducting an experimental study and artificial neural network (ANN) model.
What is the trend in sequent depth ratio for crushed aggregate?
The experimental results show that the reductions in sequent depth ratios are more in the case of crushed aggregate (4%–35%) than rounded on the same slope. By increasing bed slope, the sequent depth ratios show increasing trend in the range 3%–45%.
