Abstract A linear instability characteristic equation is developed to analyze wave propagation along a cylindrical liquid jet. It is pointed out by the solution of the equation that a perturbation to the jet propagates in either a stable or an unstable manner. In the case of stable propagation the wave speed is dispersive and is not equal to jet velocity. In the case of unstable propagation, wave speed is equal to the jet velocity and the perturbation amplitude grows with the propagation. Optimal frequency of perturbation is obtained by the determination of the maximum growth rate of disturbance with this equation. Experimental results are reported and are in good agreement with predicted value in the generation of uniform droplets. 13 Refs. (Auth abstract) XX
