Question 5.
A rectangular channel is designed with a width of 5 meters and carries a discharge of 15 cubic meters per second. Determine the critical depth and specific energy of the flow.
Show hintHide hint
Remember to derive velocity after finding depth.
Question 6.
Create a case study of an urban drainage system's performance. Explain how neglecting critical depth can lead to flooding during a storm event.
Show hintHide hint
Think about what happens to flow when systems aren’t aligned with critical conditions.
