| Résumé : |
Dimensional analysis is an important tool which enables us to group the variables involved in any physical phenomenon into dimensionaess numbers , therby reducting the number of variables and simplifying their correlation . It indicates with resonable certainly the form into which we can reduce a physical relationship involving many variables.
The different methods of dimensional analysis have been discussed in this bulletin , and illustrative example have been presented . These methods are based on the principale of dimensional homogeneity which states that each term of a dimensionally homogeneous equation must have the same dimensions . The correctness of the final result of dimensional analysis will depend on the soundness of the selection of the variables invloved in any particular phenomenon , the selection of fundamental units and the dimensionless number into which the variables have been grouped .This difficulty arises from the fact that the concerned variables can be grouped into diffirent dimensionaless numbers . |
