Q1. What is weir? How is different from notch?

Q2. How is actual discharge of weir measured?

Q3. Where is broad crested weir is used?

Q4. Does the magnitude of the flow rate affect the discharge coefficient Cod?

Q5. Does Cod increases or decrease with increasing flow rate?

Q6. What is the pattern of the water as its passes over the weir?

Q7. Would you expect the length of the weir crest to affect the discharge coefficient Cod?

Q8. What is the effect of drowning the weir (increasing the downstream depth)?
