The force of water jet on a flat surface
Kasal, Milan ; Soukup, Lubomír (referee) ; Fic, Miloslav (advisor)
This bachelor thesis discusses about the theory of fluid mechanics. In the first part of work are listed the basic hydrodynamic laws for ideal and real fluid. Further there was derived force acting on the surface. The second part is devoted to the practical use of force water jet to generate electricity and cutting of material. The objective of the last section, was practical verification of derived relations during laboratory measurements.

Calculation of the heat load of the train air conditioning unit
Kasal, Milan ; Milčák, Pavel (referee) ; Pospíšil, Jiří (advisor)
The subject of this diploma thesis is to apply the knowledge of thermodynamics when designing parameters of the train air conditioning unit. In the first part, the issue of air conditioning technology, basic types of cooling circuits and description of individual components are outlined. Furthermore, there is an overview of groups of refrigerants and their labelling. In the second part, a calculation of the heat load of the train unit for the limit design conditions of summer and winter operation, including the application of humid air theory are to be found. There is a basic procedure for designing the main components of compressor cooling, which is almost exclusively used in train applications, outlined. The last part contains the procedure for calculating the gains/losses in the distribution channels of the real air conditioning unit M7 and the evaluation of the results. In the appendix, there is an SW in MS Excel program, which can be indicatively used to calculate the total gains/losses of the distribution channels on any air-conditioning unit before the air enters into the train unit.
