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.
