Mach wave the schlieren method, to obtain data about the flow in nozzles and ducts. Mach angles may also occasionally be visualized out of their condensation in air, for example vapor cones around aircraft during transonic flight. Mach wave In fluid dynamics, a Mach wave is a pressure wave traveling with the speed of sound caused by a slight change of pressure added to a compressible flow. These weak waves can combine in supersonic flow to become a shock wave if sufficient Mach waves are present at any location. Such a shock wave is called a Mach stem or Mach front. Thus,
Mach 1 Racing Mach 1 Racing Mach 1 Racing was a NASCAR Winston Cup Series team. It was owned by Hollywood stuntman Hal Needham and actor Burt Reynolds. The team made its debut in 1981, fielding the No. 22 Skoal Pontiac driven by Stan Barrett. Barrett ran ten races for the team that season, his best finish coming at Talladega Superspeedway, where he finished 9th. Midseason, Mach 1 created a second car, the No. 33, driven by Harry Gant. Gant did not win that season, but he won three poles and had thirteen top-tens, finishing third in points. In 1982, Gant drove the
