Question

What are the limitations on dimensional analysis?

Answer 1

■ We cannot get the constant of proportionality .

■ if there are more than 3 or not then it will not help in finding powers of more than three unknowns .

■it will not help in solving mathematical equations or any constants in dimensional analysis .

Answer 2

Following are the few $\textbf{limitations of Dimensional Analysis }$:

1) It doesn't enables us to determine the value of proportionality constant, which may be a pure number or dimensionless ratio.

2) It can't be used to derive relationship involving trigo. or exponential function.

3) It fails to derive a relationship which guarantee correctness of a relation because many physical quantities have same dimensions.
