1) General definitions, physical properties of fluids, forces acting in fluid, hydraulic pressure. 2) Euler's equation of forces equilibrium, liquid under gravity field. Fluid action on the surface (straight, curved). 3) Fluid relative equilibrium (translation and rotation motion). 4) Hydrodynamic. Continuity equation. Bernoulli's equation for stable convection, velocity circulation. Euler's equation of hydrodynamic. 5) Liquid convection, potential, swirled, real fluid convection. 6) Laminar and turbulent convection. Reynold's number. Laminar convection of real fluid. Navier-Stokes's equation. 7) Fluid outflow in small and wide orifice, overhang. Fluid free convection. 8) The effect of fluid on stable and motion surface, pressure losses in pipes. 9) Bodies circumfluent, buoyancy, circulation, blade cascade. 10) Principles of hydraulic devices - blade principle. Euler' pump and turbine postulate. 11) Hydraulic solution of the simple and complex pipes. Hydraulic nets.

Learning outcomes
|
The subject introduce the students with flowing principles and liquids behaviour. The general definitions, forces acting in liquid and relative equilibrium of the liquid are introduced. The ideal and real liquid, Bernoulli's equation, laminar and turbulent convection, the hydraulic resistances and its signification for real devices. Unstable convection, the force effect of the liquid stream. The circumfluent of the bodies, physical resemblance in mechanic of fluid.
- The student will acquire knowledge of applied mechanics - hydromechanics - Knowledge of hydrostatics and hydrodynamics is the basis of study in the following years (thermomechanics, machinery mechanisms, hydraulic machines, industrial processes, etc.).
