Engineering LibreTexts The Star Conditions

The speed of sound at the critical condition can also be a good reference velocity. The speed of sound at that velocity is

    c^{*} = \sqrt{k\,R\,T^{*}}
    \label{shock:eq:starSpeedSound}  \tag{26}

In the same manner, an additional Mach number can be defined as

    M^{*} = \dfrac{U }{ c^{*}}
    \label{shock:eq:starMach} \tag{27}
