Mach Number
Mach number, abbreviated as Ma or M, a dimensionless number, is the ratio of the velocity of flow to the velocity of sound. The speed of sound in this equation is dependent on the density of the medium that the sound is traveling through. For example, the speed of sound through a solid object like a railroad track is much faster than the speed of sound through air at standard conditions.
