mach wave meaning in Hindi

Examples

1. In the subsonic case the noise is produced by eddies and in the supersonic case by Mach waves.
2. Mach waves can be used in schlieren or shadowgraph observations to determine the local Mach number of the flow.
3. The expansion " fan " is composed of Mach waves that span from the initial Mach angle to the final Mach angle.
4. When this occurs, the locus of these waves trailing behind the point creates an angle known as the Mach wave angle or Mach angle, ?
5. We know that when an object moves in a flow, it causes pressure disturbances ( which travel at the speed of sound, also known as Mach waves ).
6. With ? = 0? a normal shock is produced at the limit of the strong oblique shock and the Mach wave is produced at the limit of the weak shock wave.
7. As opposed to the flow encountering an inclined obstruction and forming an oblique shock, the flow expands around a convex corner and forms an expansion fan through a series of isentropic Mach waves.
8. On 21 November 1963, the squadron was renamed the " Sunliners " and a new insignia was approved consisting of a black background with the international orange " mach wave " design.
9. Early observations by Ernst Mach used grooves in the wall of a duct to produce Mach waves in a duct, which were then photographed by the schlieren method, to obtain data about the flow in nozzles and ducts.
10. Each wave in this case is a Mach wave, so it is at an angle \ alpha = sin ^ {-1 } ( \ frac { 1 } { M } ), where M is the Mach number immediately before the wave.
