Asked by Laiba Khan | 21 Apr, 2013, 11:21: PM
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.
