Question 1.
What is the primary purpose of experimental investigations in hydraulic engineering?
Show hintHide hint
Think about how experiments differ from theoretical calculations.
Question 2.
Define similitude in your own words.
Show hintHide hint
Consider situations where findings can be generalized.
3Question 3.
What is one primary reason experiments are essential in hydraulic engineering?
- They eliminate the need for theoretical analysis.
- They provide empirical data that is often necessary for understanding fluid behavior.
- Experiments are cheaper than simulations.
