The aim of this master thesis is to explain using of the pressure-time method, commonly known as Gibson’s method for non-stationary discharge evaluation through water machineries. The thesis included the principle of this method, deriving the method and the problems, which happened in thanks of using this method. In the second part of this thesis are in details shown results of non-stationary discharge by pressure-time method and also there is the computation of the kinetic member on the resulting discharge. Next part is about refinement of this method by evaluation Penstock factor for each segment of feeder (direct pipe, taper and pipe elbow) using MS Excel and CFD calculations. The last capture is about influence of unsteady friction. In the beginning are shown basic terms and explain the principle of this losses. In the next part is proposed numerical model of losses and their influence on calculation of total Penstock factor of feeder.
