Mach number is a unit used to measure speed. Mach, sometimes also referred to as a Mach number, is the ratio of the speed of an object to the speed of sound.[1] Mach can be abbreviated as M, and is also sometimes abbreviated as Ma. For example, Mach 1 can be written as 1 M...
To convert a speed of sound measurement to a Mach measurement, multiply the speed by the conversion ratio. One speed of sound is equal to Mach 1, so use this simple formula to convert: Mach number = speed of sound × 1 The Mach number is equal to the speed in speed of sound multipli...
a Mach number of 2 indicates a speed that is twice the speed of sound Medical Definition Mach number noun ˈmäk- : a number representing the ratio of the speed of a body to the speed of sound in a surrounding medium (as air) a Mach number of 2 indicates a speed that is...
Mach number n (Units) (often not capital) the ratio of the speed of a body in a particular medium to the speed of sound in that medium. Mach number 1 corresponds to the speed of sound. Often shortened to:Mach [C19: named after Ernst Mach] ...

The local speed of sound, and hence the Mach number, depends on the temperature of the surrounding gas. The Mach number is primarily used to determine the approximation with which a flow can be treated as anincompressible flow. The medium can be a gas or a liquid. The boundary can be tr...
Mach Number (M) = Speed of Object (V) / Speed of Sound (a) For example, if an aircraft is flying at a speed equal to the speed of sound, its Mach number would be 1.0 (Mach 1). If it is flying at twice the speed of sound, its Mach number would be 2.0 (Mach 2), and so...
The mach number M of an airplane is the ratio of its speed to the speed of sound. When an airplane travels faster than the speed of sound, the sound waves form a cone behind the airplane (see figure), The mach number is related to the apex angle θ of the cone bysin(θ )2=1M....
An all speed scheme for the Isentropic Euler equations is presented in this paper. When the Mach number tends to zero, the compressible Euler equations converge to their incompressible counterpart, in which the density becomes a constant. Increasing approximation errors and severe stability constraints...
