Challenge Problems
Push your limits with advanced challenges
A sluice gate has varying water depths of 15 m and 5 m on either side. If the average water velocity is 2 m/s, calculate the force exerted by the water on the gate. Include the required assumptions and factors used in the calculation.
💡 Hint: Think about how to set up the pressure difference calculation.
If a sluice gate must control a fluctuating flow due to seasonal rains, how would this affect your calculations for force? What factors must be reconsidered in your analysis?
💡 Hint: Consider seasonal variations in depth and how they impact average velocities.
