The Delivery of the Mixture Containing Abrasive Particles.
Hrabina, Martin ; Sluše, Jan (referee) ; Štigler, Jaroslav (advisor)
The aim of this bachelor thesis is focused on description of the transport equipment parts used in some industries for delivering of the mixture containing abrasive particles. The thesis is divided into some captures. Each of them deals with the transport issues. The first part of the thesis is focused on the flow of liquid in transport equipment. Second part describes particular parts of pumps and compares various kinds of them, highlighting their advantages. One of the significant topics of the thesis is the characterisation of pipeline using for the above mentioned transport.

The Different Kinds of the Sewage Delivery
Vosáhlo, David ; Haluza, Miloslav (referee) ; Štigler, Jaroslav (advisor)
The aim of this bachelor’s thesis is presenting the possibilities of different kinds of the sewage delivery. It is described a division and a brief overview of these types. Furthermore their main parts, function and using in practise are introduced. Pumps and their main components are depicted in the pictures or simple schemes.

Slip factor of the hydrodynamic pumps
Chromek, Lukáš ; Himr, Daniel (referee) ; Klas, Roman (advisor)
This bachelor thesis deals with the initial draft of an impeller wheel, determination of its specific energy that has a pump with infinite number of impeller blades and following correction to real specific energy of an impeller wheel pump with finite number of blades. The correction will be performed using different methods by various authors and some of the methods will also be compared during the calculation of specific energy and discharge head of pump of several real impeller wheels. Then the thesis goes on to deal with some of the effects arising from the flow of fluid in the impeller wheel that often have negative influence on above-mentioned specific energy. At the end of the thesis, there will be brief abstract on problems of the correction, simulation, and analysis of flow in a blade channel using CFD software.

Draft tube role in hydraulic turbine performance
Havlát, Pavel ; Himr, Daniel (referee) ; Rudolf, Pavel (advisor)
This bachelor’s thesis deals with the problems of draft tube. It contains basic description of draft tubes, their division and possibilities of their utilizations. Further, this thesis focuses on description of draft tubes, their efficiency, losses and ways to eliminate these losses. One part of this work also mentions basic relationships required for computing length of draft tube, velocity of the fluid in the draft tube and others.

Pump design
Mizera, Ladislav ; Svozil, Jan (referee) ; Klas, Roman (advisor)
This thesis considers the characteristic of hydrodynamic pumps. It describes the activity of these pumps and it shows the particular characteristic curves. Then the hydrodynamic pumps are divided and described. The biggest attention is attended to the vertical multistage centrifugal pump and shaft seal.

Water turbines and them use
Machát, Pavel ; Sloupenský, Zdeněk (referee) ; Himr, Daniel (advisor)
This bachelor´s thesis deals with the problems of water turbines. It contains basic division of water turbines, description of their oparations and possibilities of their utilizations. Further this thesis focuses on description of the three most used turbines i.e. Francis´s, Kaplan´s and Pelton´s turbines. As one component of this work there are also mentioned essential relations required for selection of proper type of turbine in dependency on speed, slope and flow rate.
