Density p The density of a fluid is obtained by dividing the mass of the fluid by the volume of the fluid. The denominator (m/L) is sometimes written as the Greek letter mu, and referred to as the "linear density" of the string. Sound waves (or any other form of three dimensional emanation) can be ranked by their intensity -- an objective measure of the amount of energy they carry. A dimensional equation can have the dimensions reduced or eliminated through nondimensionalization, which begins with dimensional analysis, and involves scaling quantities by characteristic units of a system or natural units of nature. This gives insight into the fundamental properties of the system, as illustrated in the examples below.
