Challenge Problems
Push your limits with advanced challenges
A hydraulic model designed with a horizontal scale of 1/250 and a vertical scale of 1/50 needs to maintain Froude number similarity. If the prototype's speed is 10 m/s, what should the model's speed be?
💡 Hint: Remember to apply the square root to the horizontal scale ratio.
If a prototype flow has a measured depth of 3 m and utilizes a specific viscosity, how do you ascertain the corresponding depth in a distorted model with a height scale of 1/30?
💡 Hint: Directly multiply the prototype depth by the height scale.
