WebDimensional analysis is a simple, clear and intuitive method for determining the functional dependence of physical quantities that are of importance to a certain process. However, in physics textbooks, very little space is usually given to this approach and it is often presented only as a diagnostic tool used to determine the validity of dependences otherwise obtained. WebThis method is simple and useful for a small number of parameters. Yet this method becomes complicated for large number of parameters. The second method, some …
