In engineering and science, dimensional analysis is the analysis of the relationships between different physical quantities by identifying their base quantities (such as length, mass, time, and electric current) and units of measurement (such as metres
The dimension of any physical quantity expresses its dependence on the base quantities as a product of symbols (or powers of symbols) representing the base quantities. Table 1.5.1 lists the base quantities and the symbols used for their dimension.
Dimensional analysis offers a method for reducing complex physical problems to the simplest (that is, most economical) form prior to obtaining a quantitative answer.
Dimensional analysis is an analytical method between different physical quantities and units of measure to understand their relationship by using fundamental dimensions, such as Mass (M), Time (T), Length (L) and Temperature (θ). In simple words, any physical equation must have the same dimension on both sides (left and right).
Dimensional analysis is a means of simplifying a physical problem by appealing to dimensional homogeneity to reduce the number of relevant variables. It is particularly useful for: checking equations; presenting and interpreting experimental data; attacking problems not amenable to a direct theoretical solution;
Dimensional analysis is used in numerical calculations, and in converting units. It can help us identify whether an equation is set up correctly (i.e. the resulting units should be as expected). …
