The method of dimensional analysis: During the school courses, the learners deal with the International System of Units (Si).All the derivative values can be expressed by the basic value units. It is necessary to remind the learners, that when doing mathematical operations with resolutions, in this case, the changes affect the dimensions of physical values, as well as it is worth to mention, that the non-dimensional values have 1 dimension, and not 0.
For indicating the dimension, let us use the following:
If we are aware of all the physical dimensions describing a specific phenomenon, then linking their dimensions and causing the right and left parts of seekable equation to have the same dimensions, we can find the required functional relationship Here the can be integers, fractional numbers or zero, and is a coefficient of variation, which, in particular cases, can be equal to one.
