Question

Given the variables: velocity (V), density ($\rho$), viscosity ($\mu$), and characteristic length (L), how many dimensionless groups can be formed?

• A. 1
• B. 2
• C. 3
• D. 4

Hint:

In dimensional analysis, always select $3$ repeating variables ($m = 3$) representing geometric, kinematic, and dynamic properties to construct your dimensionless $\pi$ groups.
These repeating variables are typically $L$, $V$, and $\rho$.
