1. Sphericity

Sphericity is a measure of how closely the shape of an object resembles that of a perfect sphere. For example, the sphericity of the balls inside a ball bearing determines the quality of the bearing, such as the load it can bear or the speed at which it can turn without failing. Sphericity is a specific example of a compactness measure of a shape. Defined by Wadell in 1935, the sphericity, Ψ {\displaystyle \Psi } , of a particle is the ratio of the surface area of a sphere with the same volume as the given particle to the surface area of the particle:

Sphericity is a measure of how spherical an object is. As such, it is a specific example of a compactness measure of a shape. Defined by Wadell in 1935, the sphericity, of a particle is: the ratio of the surface area of a sphere to the surface area of the particle: where is volume of the particle and is the surface area of the particle. The sphericity of a sphere is 1 and, by the isoperimetric inequality, any particle which is not a sphere will have sphericity less than 1.
