The error in discharge due to error in the measurement of head over a triangular notch is given by:
Show Hint
When working with flow measurements, remember the specific error formulas for different types of notches (triangular, rectangular, etc.).

- \( \frac{\partial Q}{Q} = \frac{1}{2} \frac{dH}{H} \)
- \( \frac{\partial Q}{Q} = \frac{3}{2} \frac{dH}{H} \)
- \( \frac{\partial Q}{Q} = \frac{5}{2} \frac{dH}{H} \)
- \( \frac{\partial Q}{Q} = \frac{7}{2} \frac{dH}{H} \)

The Correct Option is C
Solution and Explanation
The error in discharge due to error in the measurement of head over a triangular notch is proportional to the change in head. The specific formula for this error in discharge is given as:
\[
\frac{\partial Q}{Q} = \frac{5}{2} \frac{dH}{H}
\]
Thus, the correct answer is \( \frac{5}{2} \frac{dH}{H} \).
