Scaling Analysis
•Scale analysis, or scaling, is a convenient technique for estimating the magnitudes of various terms in the governing equations for a particular type of motion.
•In scaling, typical expected values of the following quantities are specified:
•       (1) magnitudes of the field variables;
•       (2) amplitudes of fluctuations in the field variables;
•       (3) the characteristic length, depth, and time scales on which    these fluctuations occur.
•These typical values are then used to compare the magnitudes of various terms in the governing equations.
