This paper contains results of analytic and experimental research of a discharge coefficient of nozzles with preincluded site of hydrodynamic stabilization and without it. It is shown that conditions in the entrance section of a nozzle have essential influences on the velocity profile in its output section, and, as a result, on the discharge coefficient of nozzle.
