'''Stagnation Enthalpy''' or '''total enthalpy''' (<math> h_t </math>) is the [[enthalpy]] of a flow at a [[stagnation point]]. It is the enthalpy a flow would possess if brought to rest (zero speed) [[Isentropic process#Isentropic flow|isentropically]] from speed <math>v</math>.
 
<math>
h_t = h + \frac{v^2}{2}
</math>
 
where <math>h</math> is enthalpy, and <math>v</math> is speed.
 
Stagnation enthalpy has units of energy, such that if enthalpy is thought of as the energy [[Internal Energy|associated with the temperature]] plus the energy associated with the pressure, the stagnation enthalpy adds a term associated with the kinetic energy of the fluid mass.

North Carolina is the place he enjoys most but now he is contemplating other options. For years she's been operating as a journey agent.
