Limitations of Dimensional analysis method:

  • The equations containing exponential, trigonometrically and logarithmic function do not follow this method. This method is used only for multiplication type formulation.

  • For dimensionless quantities, no information are given by this method.

  • Formula containing more than one term which are added or subtracted like s=ut+at22 also cannot be derived.
