We develop the theoretical model for the analytic description of hydrodynamicjets from protostellar disks employing the Beltrami-Bernoulli flowconfiguration of disk-jet structure. For this purpose we extend the standardturbulent viscosity prescription and derive several classes of analyticsolutions using the flow parametrization in self-similar variables. Derivedsolutions describe the disk-jet structure, where for the first time jetproperties are analytically linked with the properties of the accretion diskflow. The ratio of the jet ejection and disk accretion velocities is controlledby the turbulence parameter, while the ejection velocity increases with thedecrease of local sound velocity and the jet launching radius. Derivedsolutions can be used to analyze the astrophysical jets from protostellaraccretion disks and link the properties of outflows with the localobservational properties of accretion disk flows.
