Abstract Axially symmetric flow through a nozzle of arbitrary profile, from which a jet spouts, is theoretically analysed. As the method of analysis, superposition of source ring distribution along the nozzle wall and vortex ring distribution along the jet surface on a uniform flow is used. In the case of nozzle with a needle valve, the needle valve is substituted by source distribution along the center axis of the needle valve. As numerical example, flow through a nozzle used in Pelton wheel is analysed. The calculated results are compared with experimental ones obtained by the author, and both are satisfactorily in agreement.
