text: Stagnation temperature can be derived from the First Law of Thermodynamics.  Applying the Steady Flow Energy Equation
   and ignoring the work, heat and gravitational potential energy terms, we have:
  where:
  : mass-specific stagnation (or total) enthalpy at a stagnation point
  : mass-specific static enthalpy at the point of interest along the stagnation streamline
  : velocity at the point of interest along the stagnation streamline
  Substituting for enthalpy by assuming a constant specific heat capacity at constant pressure () we have:
  or
  where:
  : specific heat capacity at constant pressure
  : stagnation (or total) temperature at a stagnation point
  : temperature (or static temperature) at the point of interest along the stagnation streamline
  : velocity at the point of interest along the stagnation streamline
  : Mach number at the point of interest along the stagnation streamline
  : Ratio of Specific Heats (), ~1.4 for air at ~300 K
