 the static conditions, the ratio
    between the critical and static temperature and the ratio between the
    throat and static temperature must be determined. These ratios can be
    solved for by using the following equations, respectively:

    $$\textit{Tcr_o_}T_0 = \frac{2}{\gamma+1}$$
    $$\textit{Tth_o_}T_0 = \frac{1}{1+0.5(\gamma-1)*Mth^2}$$

    It is important to note that these ratios are adjusted accordingly if the
    flow at the throat is determined to be sonic (flow is choked). The static
