Limitations of dimensionless analysis:
- This method does not tell us how to determine the proportionality constant value.
- The method cannot be considered to derive composite relations. Examples s = ut + 1/2 at2 and 2as = v2 – u2.
A formula containing trigonometric function, exponential function, and logarithmic function can not derive from it.
- The method cannot be used to derive the relationship between more than three quantities.
