Opis:: The results of numerical investigations of flow through axial thrust balance holes in impeller of low specific speed pump were presented. The results were compared with available empirical investigations. It is a lack of numerical analyses in foregoing literature on flow through rotating holes. The issue is important for designing rotodynamic pumps. There are difficulties in solving the problem of precisely computing the flow in balance holes analytically.

Opis:: Centrifugal pumps are part of larger hydraulic systems. These hydraulic machines can work not only in the pumping mode but in a number of other modes whose job description is possible using complete characteristics. Some of these modes, such as the turbine mode and the reversed turbine mode, may have practical significance. Knowledge of the transition from one steady state to another state allows to estimate instantaneous values such as, e.g., flow current and torque, which may be even a few times higher than nominal. The principal issues in these transients are amplitudes of parameters of these pumps and the time constants associated with the characteristics of the system.
