Notes

  1. 1.

    In open systems, the specific enthalpy h represents the sum of specific internal energy u and specific displacement work required to bring a piece of fluid into the system against the local pressure.

  2. 2.

    Unfortunately, the specific enthalpy in closed systems does not have such a vivid meaning as in open systems.

  3. 3.

    State values are never path-dependent!

  4. 4.

    Since the isobaric thermal expansion coefficient is asked for.
