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
Mach Five car appeared to have the same functions as the Mach Five in the original series, but the buttons Speed pressed to activate them seemed more or less random, with the same button activating different abilities (or different buttons activating the same ability) in different episodes. In 2000, a prototype Mach Five with actual cutting blades was produced as a concept car. 100 production models were planned to be made in 2002 as a street legal vehicle. Built on a 2001 Chevrolet Corvette Chassis, the body was to be extensively modified to look like the Mach Five. It was to have
