Answer:
Rayleigh method, The Buckingham π Theorem, common pi group
Explanation:
Rayleigh method - The Rayleigh method is a basic technique for discovering a functional relationship in reference to a parameter of interest.
The dimensional analysis method describes a functional relationship between certain variables in context of an exponential equation
The Buckingham π Theorem The theorem notes that if a factor A1 relies on independent variable i.e. A2, A3,. An, functional bond can then be set to zero in the form f(A1, A2, A3,.–, An)= 0. If all these n parameters can be defined as m dimensional units, the pi (π) theorem states that they are grouped in respect of n-m dimensional.
There are some common pi group method which are based on Buckingham π theorem.
They are named as froude number, Reynold's number, weber number etc.
