1.2. Importance of Experimental Investigations

Try these first

1. 1.

   What is the primary purpose of experimental investigations in hydraulic engineering?

   Hint

   Think about how experiments differ from theoretical calculations.

2. 2.

   Define similitude in your own words.

   Hint

   Consider situations where findings can be generalized.

3. 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.

   Hint

   Think about the role of data in validating theories.

4. 4.

   Dimensional analysis is used to...

   • True
   • False

   Hint

   Consider how reducing complexity aids researchers.

5. 5.

   Discuss how you might apply the principles of similitude to design a new water treatment plant. Outline the steps you would take.

   Hint

   Link laboratory outcomes to variations in the environment you expect.

6. 6.

   Propose a set of experiments to determine the impact of sediment size on pressure drop in pipe flow. Include details on how you would control variables.

   Hint

   Be clear on which conditions will affect your tests and how you'll hold them steady.
