16.7.2. Economics and Construction Costs

Try these first

1. 1.

   Define Open Channel Flow.

   Hint

   Think about gravity-driven flows.

2. 2.

   What happens in a hydraulic jump?

   Hint

   Consider changes in flow characteristics.

3. 3.

   What drives open channel flow?

   • Pressure
   • Gravity
   • Centrifugal Force

   Hint

   Think about natural flow conditions.

4. 4.

   True or False: A hydraulic jump results in energy gain for the system.

   • True
   • False

   Hint

   Consider the impact on energy during transitions.

5. 5.

   Design an Open Channel for an irrigation system aimed to minimize construction costs while ensuring adequate flow. What shape would you use and why?

   Hint

   Reflect on optimal designs discussed in class.

6. 6.

   Given a hydraulic radius of 2 meters and a channel width of 4 meters, calculate the wetted perimeter and then suggest adjustments that could improve flow efficiency.

   Hint

   Utilize the formula we discussed.
