Pressure: The Bernoulli Principle and Flow Energy Conservation
The energy conservation statement that applies to a moving fluid is therefore not just about the internal energy (u) but a new quantity consisting of that energy and flow work. This quantity is the enthalpy Footnote 7 (symbol h, defined as u + ( pv ) ) and, fortunately for air, it is also proportional to just the temperature.
