Slip factor of the hydrodynamic pumps
Duda, Petr ; Archalous, Jakub (referee) ; Klas, Roman (advisor)
Bachelor thesis contains basic information about the hydrodynamic pumps. It describes the specific energy for an infinite number of very thin blade and following corrections to the finite number of blades. Part of this work is dedicated to all-weather resulting in Blade to blade channel and their effect on specific energy pump. There are illustrated by calculations of correction factors of individual authors and finally corrections are made on real three impeller wheels with a comparison of different methods.

Measuring the power of IC-engines
Adamec, Vojtěch ; Ramík, Pavel (referee) ; Štětina, Josef (advisor)
This bachelor thesis deals with topic measuring the power and the torque of internal combustion engines on chassis dynamometer. The aim of the thesis was to show advantages and disadvantages of different types of dynamometers, to make review of standards for measuring power on chassis dynamometer, effect of atmospheric conditions, resistances and slippage. Thesis also describes evolution, different designs of chassis dynamometers, effect of roller diameter to rolling resistance and deformation of tire, suitable types of dynamometers for chassis dynamometer, equipment of testing room, modes of operating and differences between static and dynamic power testing. In the end I have made prediction of incoming development devices of this type with regard to evolution of intelligent chassis control systems and electric vehicles.
