Abstract: World demand for energy is expected to grow in the future. According to hydraulic systems will be optimized in order to increase the energy production efficiency. In the light of the general energy shortage pumped storage has come to be the environmentally most compatible method of balancing sudden drops in demand or unexpected production increase from wind power stations. The contribution introduces the numerical and experimental methods used for observation of form losses in the part of surge tank-hydraulic pipe junction with nozzle. The measurements of form losses will be done at different Reynolds number. In the continuation the measurements at more and higher Reynolds number were used for extrapolation of form losses to the nature dimensions. On the basis of the extrapolation with physical model the simulation with numerical tools (CFD) was performed. In this way further adaptation of change geometries of hydraulic system is possible.
