A fall of the thin jet of viscous fluid onto the moving surface is considered. The jet is described by the effects of elongational viscosity, inertia and gravity. For the model equations we derive the boundary conditions allowing us to show existence for all the parameters, and investigate uniqueness. For the jet fall we distinguish three flow regimes, which are characterized by the convexity of the jet shape, or by an equivalent characterization of the dominant effect in the momentum transfer through the jet cross-section.
