Answer:
The dimensional equations have got the following uses:
To check the correctness of a physical relation.
To derive the relation between various physical quantities.
To convert value of physical quantity from one system of unit to another system.
To find the dimension of constants in a given relation.
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.
