Silový účinek proudu z trysky na kolmou desku

Abstract

The topic of my bachelor thesis deals with the force effect of a jet from a nozzle on a perpendicular plate. The assignment consisted of a theoretical introduction, at the beginning of which I described the basic equations of hydrodynamics, such as the Continuity Equation, Euler's equation of hydrodynamics and the momentum change theorem. Then examples of the force action of a flowing fluid based on momentum change are given. The practical part consisted in modifying and putting into operation a measuring device that had not been used for a long time. A description of the measuring device, its elements and their specific parameters, the measurement procedure and data evaluation are given. Then I made my own measurements of the force effect of the water jet on the perpendicular surface for nozzles of different diameters. In the last part I dealt with the evaluation of the obtained results and their comparison with theoretical assumptions.
