The design of Pelton turbine for given parameters
Pavlíček, Tomáš ; Veselý, Jindřich (referee) ; Haluza, Miloslav (advisor)
The aim of this bachelor's thesis is to create a project of a small Pelton’s turbine for laboratory use, focusing on the design of nozzle and blade. Designing these two parts included beam measuring, calculating the losses in the piping and finding the working point of the pump. In its first part this thesis reviews the history, the operating principle and the main parts of the Pelton’s turbine. The next part includes finding the appropriate shape of nozzle and measuring the beam, followed by the calculation of lossy coefficient and efficiency of the nozzle from the measured values. The third part is dedicated to calculation of losses in the piping and finding the working point of the pump. In the last part, blade is designed.

Design of Universal Equipment for Tire Cutting
Kohoutek, Petr ; Veselý, Oldřich (referee) ; Prokeš, František (advisor)
The main content of of this thesis is a construction design and analysis of a machine for cutting tires. The resulting solution emerges from the design options and the option that meets the best selection criteria is chosen. Then the thesis stops for a while at the choice of cutting technology and tries to exemine its suitability for cutting tires. In its other part there is an attempt to clarify the relevant parts of the machine, where the benefits of three-dimensional views is used. Basic design and check calculations are done in the selected machine parts.
