Talk:Fanno flow

Total enthalpy, or total energy?
The article states, "The Fanno line defines the possible states for a gas when the mass flow rate and total enthalpy are held constant, but the momentum varies." Shouldn't this state total energy, not total enthalpy? The enthalpy varies due to conversion of PV potential energy and U internal energy into kinetic energy, but the adiabatic condition requires that the total energy be held constant. --Mr Wednesday (talk) 16:27, 10 April 2013 (UTC)
