Educational goal:

Provide basic knowledge, competence and academic skills to students about liquids and gases, their properties and behavior in different conditions of internal and external flows. Development of creative abilities and mastering specific practical skills on hydrostatic law, fluid pressure on flat and curved surfaces, swimming, relative resting of the fluid. Introduction to maintenance laws and equations that have been followed by the historical development of fluid mechanics: Euler's equation for a quasi-fluid, for flowing ideal fluid, Bernoulli equation. Application of basic laws and equations for the analysis of static and dynamic problems of fluids. Introduction of the importance of fluid flow measurement and application in industry. Determination of losses in power systems and pipelines.

Educational outcome:

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).

Course content:

The subject and a brief historical development of Fluid Mechanics. General concepts. Physical properties of fluids. Molecular structure - microstructure. The division of physical properties. Pressure. Density. Compressibility. Speed of sound. Viscosity. Surface tension, capillarity and critical pressure. Cavitation. Fluid statics. The hydrostatic pressure. Euler equations for a static fluid. Pressure distribution in liquids and gases in the field of gravity. Fluid pressure on a flat surface. Hydrostatic forces on flat surfaces. Hydrostatic forces on curved surfaces. Buoyancy. Fluid as rigid body under uniform linear acceleration. Fluid as rigid body under rotation. Fluid Kinematics. Dynamics of ideal fluid. Euler equations.Bernoulli integral of Euler equations. Bernoulli equations. Correction factor of kinetic energy. Pipe problems - a form with losses. The coefficient of friction. The method of approximation. Pipeline with turbomachinery, the critical pressure, closed pipeline system. The energy diagram. Complex pipelines. Flow through the holes and sockets. Flow with the variable level. Flow rate measurement.

Teaching methods:

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). Practice is divided into computing practice (10 weeks) and laboratory (5 weeks). Computing practice accompanies lectures and examination problems are solved on board by gradual display of results. Laboratory practice is held at once for 6 hours, where 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.
