Learning outcomes

Objectives: The subject introduces students to the importance of fluid flow and behavior. It defines basic terms, forces acting in fluid and relative equilibrium of fluids (liquids). Flow of ideal and real fluid, Bernoulli equation, laminar and turbulent flow, hydraulic resistances and their importance for real machines. Continuous flow, force effect of liquid flow. Characteristics of body wrap, physical similarity in fluid mechanics.
Students will learn the basics of hydrostatics and hydrodynamics, they will be able to derive basic relations for expressing processes, relationships and dependencies in hydromechanics. They will then be able to apply this knowledge both at the theoretical level and further develop it, and work with them in specific technical applications in practice. The foundations are then used in further studies, for example in hydraulic mechanisms, in thermomechanics, etc.
