### Subject aims expressed by acquired skills and competences

The goal is to familiarize students with experimental and numerical methods for solving the application of Hydromechanics to the fire equipment issue. Students will analyze the characteristics of series and parallel arranged lines, hydraulic hammer, pump specific energy separate and arranged in series and parallel case and power flow on surface, where they will at first dealt with a steady state follows a time-dependent tasks. They will separately compile various located tasks in the software Matlab-Simulink and then compare the results with measured values from the experiment, the student performed in the laboratory department. Results will be compared and evaluated at the defense of the test.
