The discharge through a V-notch weir varies as___________________?
Correct answer: C. H5/2
- A. H3/2
- B. H1/2
- C. H5/2
- D. H2/3
Explanation
Integrating the elemental discharge across a V-notch gives Q proportional to H^(5/2). Therefore the discharge follows the H5/2 dependence, not the rectangular-weir H3/2 dependence.
