Answer:

[tex]Ma=\frac{260}{330} \\Ma=0.7878[/tex]

So, Ma < 1  Flow is Subsonic

Explanation:

Mach Number:

Mach Number is the ratio of speed of the object to the speed of the sound. It is used to categorize the speed of the object on the basis of mach number as sonic, supersonic and hyper sonic. (It is a unit less quantity)

Mach < 1       Subsonic

Mach > 1       Supersonic

Ma= Speed of the object/Speed of the sound

[tex]Ma=\frac{260}{330} \\Ma=0.7878[/tex]

So, Ma < 1 Flow is Subsonic
