10. What is the main advantage of the use of a triangular notch or weir for flow measurement over a rectangular notch or weir?
- Triangular notches are easier to fabricate
- Triangular notches can handle higher flow rates
- Triangular notches have a wider range of applications
- Triangular notches provide better accuracy at low flow rates
Answer: D) Triangular notches provide better accuracy at low flow rates.
Explanation:
Due to their unique shape, triangular notches are more accurate than rectangular notches at measuring low flow rates. In the low flow system, where rectangular notches may have constraints, the triangular design improves measurement accuracy.
