In physics, a characteristic length is an important dimension that defines the scale of a physical system. Often, such a length is used as an input to a formula in order to predict some characteristics of the system, and it is usually required by the construction of a dimensionless quantity, in the general framework of dimensional analysis and in particular applications such as fluid mechanics.
A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre. The distance between any point of the circle and the centre is called the radius. The length of a line segment connecting two points on the circle and passing through the centre is called the diameter.
In geometry, the circumference (from Latin circumferens, meaning "carrying around") is the perimeter of a circle or ellipse. The circumference is the arc length of the circle, as if it were opened up and straightened out to a line segment. [1] More generally, the perimeter is the curve length around any closed figure.
Perimeter is the distance around a two dimensional shape, a measurement of the distance around something; the length of the boundary. A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference.
The characteristic length depends on the geometry. For a circular pipe the characteristic length would be the diameter. For non circular ducts, the characteristic length would be: L=4A/p where A is the cross-sectional area of the duct, P would be the wetted perimeter. Note that for a circular pipe: L=4*(pi*D^2/4)/(pi*D) = D
This selection of characteristic length can be used to present a distinction between Strouhal number and reduced frequency: St = k A π c , {\displaystyle {\text{St}}={\frac {kA}{\pi c}},} where k is the reduced frequency , and A is amplitude of the heaving oscillation.

Ptolemy used a circle of diameter 120, and gave chord lengths accurate to two sexagesimal (base sixty) digits after the integer part. [2] The chord function is defined geometrically as shown in the picture. The chord of an angle is the length of the chord between two points on a unit circle separated by that central angle.
