Mach Number

It is defined as the speed of the object (v) to the speed of sound (a) in the given medium.
Since it is the ratio of speeds, it doesn’t have a unit. In aerodynamics, the speeds of bodies moving in a fluid medium are classified into different categories on the basis of Mach Number. Mach Number is named after the German scientist Ernst Mach.
