A Galilei invariant field theory, developed in a previous paper, is here extended further to more general cases of barotropic fluid, and to take into account the interaction between the fluid and the excitation of its constituent. The result resembles the two fluid model of the superfluidity. The discussion is restricted to the classical fluid, and no attempt is made at quantizing it, though the Hamiltonian formalism is briefly discussed.
