Vliv zrnitosti krycí vrstvy na hydraulickou drsnost dna / Change of bed roughness by particle separation in the surface layerRoháčová, Denisa January 2013 (has links)
This master thesis is divided into two parts: theoretical and practical one. In the theoretical part there is described hydraulic roughness, velocity distribution in the case of hydraulically rough surface and the process of grain sorting in surface layer. The practical part of the thesis resolves the influence of surface layer on hydraulic roughness of bed, expressed by Nikuradse sand grain size ks. The results are formulas explaining dependence of ks on characteristic grain size dx from grain-size distribution curve and comparison with coefficient ks according to different authors.

Automatizované pracoviště pro měření vzduchotechnických veličin / Automatized working place for measuring of airflow parametersSmělý, Jakub January 2013 (has links)
This thesis describes the design work for the measurement of air values. The first part describes the airflow, pressure build-up in pipes and losses due to airflow losses. There is also a description of fans and explain their characteristics depending on the pressure generated by airflow. The next part describes the design of the measuring chamber, electronics and control for fully automatic measurement of air quantities.
