Question

If the Mach number tends to infinity, what would be the measured density?

• A. Infinity
• B. Zero
• C. \(\sqrt{6}\) times higher than initial density
• D. 0.378 times higher than initial density

Hint:

As Mach number increases, shock strength increases and static properties decrease.

Answer 1

The Correct Option is B

At very high Mach numbers (approaching infinity), the flow becomes highly compressible, and the static pressure and density approach zero.
