Meaning of número mach




Felipe Lorenzo del Río

número mach
  17

Or simply Mach in honor of Austro-Hungarian physicist Ernst Mach (pronounced Maj). This number indicates the speed of an object relative to the speed of sound in the same medium. Thus Mach 1 indicates a displacement at the speed of sound. If an airplane moves with speed Mach 2 it would exceed twice the speed of sound.
