Die Strömungsgeschwindigkeit c ist sehr groß im Vergleich zur Schallgeschwindigkeit a. Die Änderungen von c sind sehr gering, so dass die Änderungen der Machzahl Ma fast ausschließlich das Ergebnis der Änderungen der Schallgeschwindigkeit a sind.
The velocity c is very large compared to the speed of sound in a. The changes of c are very low, so that the changes of the Mach number are almost exclusively the result of changes of velocity of a MA.
The flow velocity c is very large compared to the speed of sound a. The changes of c is very low, so that the changes in the Mach number Ma are almost entirely the result of changes in the speed of sound a.
The velocity c is very large compared to a sound. The changes of c are very small, so that the changes of the Mach number ma almost exclusively, the result of the speed of sound changes a.
