Exercise 15
Considering the following photographs of Figure 38, repeated here for convenience:
- Conceptually, how would the wetted perimeter and the effective hydraulic radius of each of the two conduit passages be calculated at the flow condition shown?
- Conceptually, how would the wetted perimeter and the effective hydraulic radius of each of the two conduit passages would be calculated if the passages were completely water filled?
- How might wetted perimeter, flow velocities, and discharge progressively change for the passage on the left as it fills with water during a storm?
- How might wetted perimeter, flow velocities, and discharge progressively change for the passage on the right as it fills with water during a storm? Hint: Keep the presence of the rectangular open channel, the broad rounded sediment banks, and the flattened elliptical shape of the upper half of the conduit in mind.
