Expert Answer:

Limitations of dimensional analysis:

  • We can get any information about the dimensionless constants.
  • If a quantity depends on more than three factors having dimensions, the formula can't be derived.
  • The formulae containing trigonometric functions,exponential funtions etc can not be derived.
  • It gives no information whether a physical quantity is a scalar or a vector.
