Question 1.
What is the formula for the Froude number?
Show hintHide hint
Think about the forces involved in fluid flow.
Question 2.
What do we achieve by using model scales?
Show hintHide hint
What is the benefit of scaling down a model?
3Question 3.
What role does the Froude number play in hydraulic modeling?
- It determines temperature
- It scales force
- It maintains gravity similarity
Show hintHide hint
Think about which forces are significant in fluids.
4Question 4.
True or False: Distorted models always maintain geometric similarity.
- True
- False
Show hintHide hint
Recall the definition of distorted models.
Question 5.
Given a river's dimensions, you must create a model with a horizontal scale of 1/100 and a vertical scale of 1/300. Analyze how this affects your Froude number scaling.
Show hintHide hint
Use the ratios derived from the model dimensions.
Question 6.
How would you design a hydraulic model that accurately replicates a turbulent flow scenario, considering both Froude and Reynolds numbers?
Show hintHide hint
Remember, turbulent flow needs high ratios - what aspects would you control?
