Reference Temperature in Hypersonic Flow Formulas

Reference Temperature is the Temperature at which the values of the physical properties of a fluid are chosen in dimensionless equations for the heat transfer, and resistance. And is denoted by T_ref. Reference Temperature is usually measured using the Kelvin for Temperature. Note that the value of Reference Temperature is always positive.
