Consider the following measuring structures:
1. Submerged broad-crested weir
2. Free broad-crested weir
3. Free sharp-crested weir
4. Free ogee spillway
The correct sequence of the increasing order of the discharge coefficient of these structures is 
  • a)
    1, 2, 4, 3
  • b)
    2, 1, 3, 4
  • c)
    2, 1 , 4, 3
  • d)
    1, 2, 3, 4
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
Consider the following measuring structures:1. Submerged broad-crested...
For ogee spillway, Cd1 = 1.19 Cds
Cds is the discharge coefficient for sharp - crested weir. So 4 will come after 3.
The classification of weir is:

Further submerged weirs have lesser coefficient of discharge compared to free weirs. So, 2 will come after 1.

The Discharge Coefficients of Measuring Structures

Submerged Broad-Crested Weir:
- A weir is a structure placed across a river or open channel to measure the flow rate of water.
- In a submerged broad-crested weir, the water flows over the weir, and the crest of the weir is completely submerged.
- The discharge coefficient of a submerged broad-crested weir is the lowest among the given structures as it has the least hydraulic head.

Free Broad-Crested Weir:
- In a free broad-crested weir, the water flows over the weir, and the crest of the weir is above the water surface.
- The discharge coefficient of a free broad-crested weir is higher than that of a submerged broad-crested weir.

Free Sharp-Crested Weir:
- In a free sharp-crested weir, the water flows over a sharp edge, and the crest of the weir is above the water surface.
- The discharge coefficient of a free sharp-crested weir is higher than that of a free broad-crested weir.

Free Ogee Spillway:
- An ogee spillway is a curved structure that allows water to flow over a dam or weir.
- The discharge coefficient of a free ogee spillway is the highest among the given structures as it has the highest hydraulic head.

Increasing Order of Discharge Coefficient:
- The correct sequence of the increasing order of the discharge coefficient of these structures is:
- Submerged broad-crested weir (1) < free="" broad-crested="" weir="" (2)="" />< free="" sharp-crested="" weir="" (3)="" />< free="" ogee="" spillway="" />
- Therefore, the correct answer is option 'D'.
