What is the Mach angle for a flow at Mach 2.0 ?
Mach angle for a flow is defined as \mu =sin^{-1}\left ( \frac{1}{M} \right )
\\\Rightarrow \mu =sin^{-1}\left ( \frac{1}{2.0} \right ) \\\Rightarrow \mu =sin^{-1}\left ( 0.5 \right ) \\\Rightarrow \mu =30^{\circ}
Therefore Mach angle for a flow at Mach 2 is 30 degrees.
