The characteristic Mach number is constant for a given value of temperature and gamma.

The characteristic Mach number is constant for a given value of temperature and gamma. Correct Answer False

The defined M* or the characteristic Mach number depends upon the Mach number, for any given gamma. It changes if the Mach number is changed, which changes by changing the flow speed at any temperature. Hence, the given statement is false.
