Applications of Dimension Analysis
To derive the relation between physical quantities in physical phenomena
To change units from one system to another
To check the consistency of a dimensional equation
To design experiments, optimize processes, and verify calculations
To develop and simplify equations
Limitations of Dimensional Analysis
It doesn't give information about the scalar or vector identity of a physical quantity.
Dimensional analysis cannot confirm the validity of a relationship of the physical quantities.
Cannot derive trigonometric, exponential, and logarithmic functions.
It is impractical for the correlation of more than three parameters.
Doesn't provide information about the dimensional constant.
