Challenge Problems
Push your limits with advanced challenges
Design an open channel that ensures the Froude number does not exceed 2 during peak flow. Calculate the dimensions based on given flow characteristics.
💡 Hint: Think about how to manipulate flow depth and velocity effectively.
A sluice gate operation transitions flow from 1 m depth at 5 m/s to new conditions downstream. Calculate the new depth and velocity, assuming critical flow must be maintained.
💡 Hint: Focus on specific energy principles and continuity equations.
