6. Maximum Discharge Condition for Triangle Duct

Try these first

1. 1.

   Calculate the area of a triangular duct with base = 4m and height = 3m.

   Hint

   Use the area formula for triangles.

2. 2.

   What is Manning's equation used for?

   Hint

   Recall the context we discussed it in.

3. 3.

   What does 'n' represent in Manning's equation?

   • Cross-sectional Area
   • Roughness Coefficient
   • Hydraulic Radius

   Hint

   Think about how surface materials affect water flow.

4. 4.

   True or False: The hydraulic radius is calculated as A divided by P.

   • True
   • False

   Hint

   Consider the definitions we discussed in class.

5. 5.

   In a triangular duct of height 2m and base 3m with a slope of 1%, compute the discharge using different values for the roughness coefficient.

   Hint

   Also remember to calculate the wetted perimeter before finding discharge.

6. 6.

   Evaluate how potential changes in triangular duct height affect overall discharge when maintaining a constant slope of 0.02.

   Hint

   Test various heights while monitoring changes in results for Q.
