In a horizontal, frictionless, rectangular channel, water is flowing. A smooth hump is built on the channel floor at a section, and its height is gradually increased to reach choked condition in the channel. Let's analyze the correct statements for the choked and unchoked conditions in the channel:
1. In choked condition, y2 is equal to the critical depth if the flow is supercritical or subcritical.
- In a choked condition, the flow velocity reaches its maximum possible value. If the flow is supercritical, the depth of water at section y2 will be equal to the critical depth, which is the depth at which the flow velocity equals the critical velocity. Similarly, if the flow is subcritical, the depth of water at section y2 will also be equal to the critical depth. Therefore, statement A is correct.
2. In choked condition, y1 decreases if the flow is supercritical and increases if the flow is subcritical.
- In a choked condition, the flow velocity is at its maximum, and the depth of water at the upstream section y1 has to adjust accordingly. If the flow is supercritical, the depth of water at section y1 will decrease to accommodate the increased velocity. On the other hand, if the flow is subcritical, the depth of water at section y1 will increase to adjust to the reduced velocity. Therefore, statement B is also correct.
3. In unchoked condition, y1 remains unaffected when the flow is supercritical or subcritical.
- In an unchoked condition, the flow velocity is below the maximum possible value. The depth of water at the upstream section y1 is determined by the flow conditions and the channel geometry, but it is not influenced by whether the flow is supercritical or subcritical. Therefore, statement C is correct.
4. In choked conditions, y1 increases if the flow is supercritical and decreases if the flow is subcritical.
- This statement is incorrect because in choked conditions, the depth of water at the upstream section y1 decreases if the flow is supercritical and increases if the flow is subcritical. Therefore, statement D is incorrect.
To summarize, the correct statements for the choked and unchoked conditions in the channel are:
- In choked condition, y2 is equal to the critical depth if the flow is supercritical or subcritical.
- In choked condition, y1 decreases if the flow is supercritical and increases if the flow is subcritical.
- In unchoked condition, y1 remains unaffected when the flow is supercritical or subcritical.
1. In choked condition, y2 is equal to the critical depth if the flow is supercritical or subcritical.
- In a choked condition, the flow velocity reaches its maximum possible value. If the flow is supercritical, the depth of water at section y2 will be equal to the critical depth, which is the depth at which the flow velocity equals the critical velocity. Similarly, if the flow is subcritical, the depth of water at section y2 will also be equal to the critical depth. Therefore, statement A is correct.
2. In choked condition, y1 decreases if the flow is supercritical and increases if the flow is subcritical.
- In a choked condition, the flow velocity is at its maximum, and the depth of water at the upstream section y1 has to adjust accordingly. If the flow is supercritical, the depth of water at section y1 will decrease to accommodate the increased velocity. On the other hand, if the flow is subcritical, the depth of water at section y1 will increase to adjust to the reduced velocity. Therefore, statement B is also correct.
3. In unchoked condition, y1 remains unaffected when the flow is supercritical or subcritical.
- In an unchoked condition, the flow velocity is below the maximum possible value. The depth of water at the upstream section y1 is determined by the flow conditions and the channel geometry, but it is not influenced by whether the flow is supercritical or subcritical. Therefore, statement C is correct.
4. In choked conditions, y1 increases if the flow is supercritical and decreases if the flow is subcritical.
- This statement is incorrect because in choked conditions, the depth of water at the upstream section y1 decreases if the flow is supercritical and increases if the flow is subcritical. Therefore, statement D is incorrect.
To summarize, the correct statements for the choked and unchoked conditions in the channel are:
- In choked condition, y2 is equal to the critical depth if the flow is supercritical or subcritical.
- In choked condition, y1 decreases if the flow is supercritical and increases if the flow is subcritical.
- In unchoked condition, y1 remains unaffected when the flow is supercritical or subcritical.
