4Question 4.
True or False: Selecting repeating variables can include dependent variables.
- True
- False
Show hintHide hint
Reflect on the definitions of independent and dependent variables.
Question 5.
Given variables of fluid flow: speed (V), density (ρ), viscosity (μ), and pipe diameter (D). Distinguish independent from dependent variables and formulate Pi terms.
Show hintHide hint
Use properties of independence and check dimensional homogeneity.
Question 6.
Analyze a complex flow where the wave period (T) depends on wavelength (λ), density (ρ), depth (D), and gravity (g). Find Pi terms and express them dimensionally.
