Assessment of minimal night-flows in the water supply systems
Zvejška, Tomáš ; Tuhovčák, Ladislav (referee) ; Ručka, Jan (advisor)
This Diploma thesis deals with minimum night flows issue. Basic findings about minimum night flows were summarized in the introductory part of thesis. Findings like the minimum night flow components, affecting parameters and used methodologies for assessment of minimal night flows. In the practical part of this thesis was this knowledge applied to real water distribution system in the municipality Hrádek u Sušice. The part of this thesis was also determinate the measurement accuracy of used water meter, which was formerly installed at the outlet in the Hrádek water tank. Measurement errors was determinate for the flow values, that are close to the real measured minimum night flow data in the water distribution system in municipality Hrádek u Sušice.

House water meters
Zvejška, Tomáš ; Tureček, Jan (referee) ; Ručka, Jan (advisor)
Bachelor´s thesis is focused to measurement accuracy of House water meters at very low flows. There are some errors during these flows. It´s not known what the values of these errors become, yet. The goal of my thesis is assessment of these errors. Results have been achieved through laboratory measurements.

Measurements of small flow in water service connections
Stehlíková, Veronika ; Ševčík, jiří (referee) ; Tuhovčák, Ladislav (advisor)
In the first part of this thesis the basic information about the losses of water and their reporting are described. There are presented the means and methods of reducing water losses and their suitability for use. Finally, general information about water meters are presented and the UFR device is briefly described. The second part of the thesis is devoted to testing water meter and UFR device on specific water connection in a family house. The thesis resulted in the author's general recommendations for owners and operators of water supply networks.

Analysis of Water Consumption in Brno
Růžička, Jaroslav ; Kučera, Tomáš (referee) ; Tuhovčák, Ladislav (advisor)
Water consumption is the amount of water removed by the consumer from water disstribution network. During the transportation inside water disstribution network occur losses. Assesing these losses is one of the main responsibillities of the water supplier. We can show the amount of water lost by using several different methods. Values used to describe the amount of water lost can be often replaced by percentual ratio of water produced to water lossed.

Evaporative water loss in terrestrial vertebrates
Demešová, Jana ; Starostová, Zuzana (advisor) ; Vohralík, Vladimír (referee)
Evaporative water loss affects physiology, ecology and evolution of individual organisms. This wok summarizes the knowledge about water loss in main groups of terrestrial vertebrates. In addition to physiological processes, it also follows evolutionary trends through adaptations created as a barrier against the water loss or as a method of cooling by evaporation. From an ecological point of view, it examines whether these adaptations have enabled some of them to inhabit extreme habitats. The topic of water loss by evaporation interferes with other topics such as thermoregulation or metabolism. Key words: evaporation, water loss, aridity, thermoregulation, metabolism, vertebrate
