In this paper, water turbines are divided and described. Water power and turbine development are generally described. For each turbine, the principle of operation, their characteristics and parts are briefly presented. An experiment was conducted on model of Pelton’s H19 turbine. Laboratory measurements were performed under three different conditions. Through laboratory measurement, which consisted of measuring the number of revolutions and force on two dynamometers at the initial set flow and pressure, a further computational test using the stated values followed. The calculated measurement consisted of testing the torque, mechanical and hydraulic power as well as the efficiency coefficient. Most of the computational part is also accompanied by diagrams at given or calculated values. From the measured data and calculated values, it was concluded that the results of the second experiment, ie measurements, are the most favorable choice. The second measurement resulted in the highest power and the highest coefficient of efficiency, which leads us to the conclusion that in a given range, the mean pressure and mean flow are the best choice when using this turbine. The efficiency coefficient was 21.137 percent, which is an extremely low value compared to Pelton turbines used in hydraulic plants. The lower values of power and efficiency are a consequence of the given laboratory drop in water, which could not be influenced, and the construction of the turbine, which was not sensitive enough at lower flows. Also, from the obtained results, it is possible to conclude that with the laboratory H19 Pelton turbine there are large losses between the inlet of the water jet and the transmission of force on the rotor.
