Dimensional Analysis can’t derive relation or formula if a physical quantity depends upon more than three factors having dimensions. It can’t derive a formula containing trigonometric function, exponential function, and logarithmic function and it can’t derive a relation having more than one part in an equation.
The main advantage of a dimensional analysis of a problem is that it reduces the number of variables in the problem by combining dimensional variables to form non-dimensional parameters. By far the simplest and most desirable method in the analysis of any fluid problem is that of direct mathematical solution.
Beside this, What are the limitations of dimensional formula Class 11?
What are the limitations of dimensional analysis? The limitations of dimensional analysis are: (i) We cannot derive the formulae involving trigonometric functions, exponential functions, log functions etc., which have no dimension. (ii) It does not give us any information about the dimensional constants in the formula.
Likewise, What are the applications and demerits of dimensional analysis?
(i) The value of dimensionless constants cannot be determined by this method. (ii) This method cannot be applied to equations involving exponential and trigonometric functions. (iii) It cannot be applied to an equation involving more than three physical quantities.

What is the importance of dimensional analysis?
Dimensional analysis can be used as a tool to construct equations that relate non-associated physico-chemical properties. The equations may reveal hitherto unknown or overlooked properties of matter, in the form of left-over dimensions — dimensional adjusters — that can then be assigned physical significance.

What is the main use of dimensional analysis?
We make use of dimensional analysis for three prominent reasons: To check the consistency of a dimensional equation. To derive the relation between physical quantities in physical phenomena. To change units from one system to another.
Why is dimensional analysis important in science?
Dimensional Analysis is a way chemists and other scientists convert units of measurement. We can convert any unit to another unit of the same dimension. This means we can convert some number of seconds into another unit of time, such as minutes, because we know that there are always 60 seconds in one minute.
