Challenge Problems
Push your limits with advanced challenges
A concrete channel has a width of 4 m and a depth of 2 m, with a slope of 0.01. If the Manning's roughness coefficient is 0.025, calculate the flow rate Q and the Froude Number.
💡 Hint: Remember, find the hydraulic radius first for precise calculations.
Using an uneven channel profile, calculate the Froude Number at three different locations where depths and velocities are varying. How does the channel shape influence those numbers?
💡 Hint: Analyze how all measurements interact in the overall channel flow.
