The objective of the course is acquiring knowledge, competencies and academic skills of students on liquids and gases, their properties and behavior in different conditions of internal and external flows. The course envisages the development of creative abilities and mastering specific practical skills in the field of application of fluid mechanics to solve specific problems. Achieving the ability for practical determination of certain flow field properties.

The learning outcomes are: To know, understand and apply the basic concepts of Fluid Mechanics to carry out professional engineering activities in the field of fluids. To develop critical thinking and to be able to analyse qualitatively and quantitatively the problem situation, propose hypotheses and solutions. Use specific vocabulary and terminology of fluid mechanics. Work efficiently in a group, integrating skills and knowledge to make decisions in the performance of fluid mechanics tasks. Acquisition of knowledge for solving problems in liquids and gases at rest and in motion (dimensioning of containers and reservoirs, dimensioning of pipelines, determination of flow characteristics).

The course is held by using modern equipment (all lectures are done in Power Point), but also by using classical methods – chalk and blackboard. There are a number of movies in fluid mechanics being presented to the students, but also assigned for homework. Objects related to the lectured units are brought to class when possible (pipe elements, measurement instruments). Exercises are divided into solving problems - calculation practice (10 weeks) and laboratory (5 weeks). Calculation practice accompanies lectures and problems are solved on board by gradual display of results. At laboratory exercises students carry out experiments and use obtained results to get end results and to draw graphs. Students have to complete practice for homework in order to defend their results and get approval for them at the next laboratory practice class.
