If the number of variable involved in a physical phenomenon are known, then the relation among the variables can be determined by the following two methods:

1) Rayleigh's method and 2) Buckingham's Pi theorem

Rayleigh's method:

This method is used for determining the expression for a variable which depends upon maximum three or four variables only. If the number of independent variables becomkes more than four, then it is very difficult to find the expression for the dependent variables.
