12. When dealing with irregular flow patterns, why could a triangular weir be favored over a rectangular weir?
- Triangular weirs are less affected by irregular flow
- Triangular weirs can handle higher flow rates
- Triangular weirs have better visibility
- Triangular weirs are less expensive to install
Answer: A) Triangular weirs are less affected by irregular flow.
Explanation:
The triangular design helps the flow to transition more smoothly over the crest, reducing the impact of turbulence and imperfections in the flow and leading to more accurate measurements.
