The present paper discusses the hydrodynamics and propulsive properties when a jet of fluid is ejected from the opening of a tube. Formulas for the calculation of the thrust are provided and the basic equations for the horizontal rectilinear motion of a rigid torpedo-like body are studied in some detail. The results may be applied to investigate in an elementary way the locomotion of certain aquatic animals.
