Define Dimensional Analysis and write down its uses.

Dimensional analysis is a mathematical technique which makes the use of the study of the dimension for solving several engineering problems.

Uses of Dimensional Analysis:

To test the dimensional homogeneity of any equation of fluid motion.
To derive rational formula for a flow phenomenon.
To plan model test and present experimental results in a systematic manner.
To derive equations expressed in terms of non-dimensional parameters to show the relative significance of each parameter.
