What is (Subject: Thermodynamics)

    What is the interpretation of enthalpy in an isothermic system?

    I ask as I am trying to understand what [tex]\int p d\left(\frac{1}{\rho}\right) [/tex] means in the context of a Lagrangian fluid.

    Enthalpy is the total energy in the system, plus the work required to move the surrounding environment out of the way: H=U+PV.
