The transonic equation is derived for several dispersive compressible fluids. A similar transformation by Tomotika--Tamada is still applicable and provides nozzle flow solutions. When the coefficient of the dispersion term is positive, the choked flow with a shock wave in the divergent section in ordinary gasdynamics is replaced by the flow with a wavetrain and an appreciable change in the flow rate. There is a critical state of maximum mass flow as in ordinary gasdynamics. For negative coefficients of the dispersion term, the features of the low supersonic flow resemble that of the high subsonic flow for positive coefficients. The detailed calculation shows that the weak dispersion and the two-dimensional structure play an important role in the nozzle flow near the critical state.
