Challenge Problems
Push your limits with advanced challenges
Given an upstream flow depth of 3 m and velocity of 5 m/s, calculate the downstream flow depth when the flow transitions to a subcritical state. Use conservation equations.
💡 Hint: Start by using F = v/sqrt(g*y) to find the initial conditions.
Discuss the design implications of hydraulic jumps in a spillway that experiences high flows. What would engineers need to consider?
💡 Hint: Consider both flow conditions and the physical environment.
