Challenge Problems
Push your limits with advanced challenges
A sluice gate with an upstream water level of 10 m and downstream level of 2 m must hold a force against flow. Calculate this force considering flow velocities.
💡 Hint: Set your control volumes properly and balance forces using pressure differences.
Given a specific energy content and varying flows, create a scenario to evaluate how different beta factors impact overall flow calculations.
💡 Hint: Control volume balancing will play a crucial role here.
