Question 1.
What does dimensional analysis help researchers achieve?
Show hintHide hint
Think about how many experiments are needed.
Question 2.
Define the term 'similitude'.
Show hintHide hint
It’s about making lab results applicable outside the lab.
3Question 3.
What is the primary goal of conducting experiments in hydraulic engineering?
