Mach number Mach number In fluid dynamics, the Mach number (M or Ma) (; ) is a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound. where: By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). The local speed of sound, and thereby the Mach number, depends on the condition of the surrounding medium, in particular the temperature. The Mach number is primarily used to determine
Ford Mustang Mach 1 If released, it will be powered by a tuned version of the 5.0-liter Coyote V8 engine, and is likely to slot between the regular Mustang GT and the more powerful Shelby GT500. Ford Mustang Mach 1 The Ford Mustang Mach 1 is a performance-oriented option package of the Ford Mustang, originally introduced by Ford in August 1968 as a package for the 1969 model year. The Mach 1 title adorned performance oriented Mustang offerings until the original retirement of the moniker in 1978. As part of a Ford heritage program, the Mach 1 package returned in 2003 as a high
