Rayleigh's method of dimensional analysis

Rayleigh's method of dimensional analysis is a conceptual tool used in physics, chemistry, and engineering. This form of dimensional analysis expresses a functional relationship of some variables in the form of an exponential equation. It was named after Lord Rayleigh.

The method involves the following steps:

Drawback – It doesn't provide any information regarding number of dimensionless groups to be obtained as a result of dimension analysis
