Course objectives supported by learning outcomes
In subject of Fluid mechanics students obtain the knowledge of application of conservation laws and force balance in case of steady and unsteady fluid flow. They will realize simple experiments to understand the theory. They will be able to solve the fluid flow mechanics problems, pressures and pressure forces in case of steady and unsteady flow.
Syllabus
  • The physical properties of liquids, dimensions, dimensions homogeneity, units, Hydrostatics, Pascal law, Archimedes' law Euler's equation of hydrostatics,
  • Fluids in relative calm during direct and rotating motion of container.
  • Second Newton law,. Introduction to fluid flow continuity equation and Bernoulli's equation for ideal fluid flow, limits of using Bernoulli’s equation, energetic equations, change to motion.
  • Measurements of velocity, flow capacity (Pitot’s and Venturi’s tube, Static, dynamic and total pressure) Liquid outflow from a small orifice (free, afloat, jet, coeficient of outflow, contraction and velocity)
  • Quasistacional liquid outflow from conteiners (emptying of containers, balance of liquid level,)
  • Steady flow in pipes, laminar and turbulent flow in pipes (laminar and turbulent examples of flow in pipes)
  • Unsteady flow of an incompressible fluid in pipeline, water hammer
  • Bernoulli equation for the rotating channel, centrifugal pumps, pump’s characteristic curves, pumps in the piping system, Euler’s equitation for turbines.
  • Force effects of the flowing liquids on surfaces (static and in motion), optimal station of Pelton turbine, jet and rocket engine.
  • Laminar flow in pipes of circular cross section, in thin slot
  • Turbulent flow ( characteristics of turbulence, turbulent Reynolds pension)
  • Body wrap, boundary layer, pressure resist, surface friction drag.
  • The physical similarity laws, Dimensional analysis.
