Block I. FLUID STATIC | Unit 1: FUNDAMENTALS OF MECHANICAL FLUID. Brief summary of the history of fluid mechanics (hydraulic versus fluid-mechanical). Definition of fluid. Newtonian and non-Newtonian fluids. Dimensional analysis and metric systems: International System (S.I.), Technical System (S.T.) and Cegesimal System (CGS). Fluid properties: absolute and specific density, pressure, compressibility, specific weight, definition of viscosity (although it will be explained in more detail in fluid dynamics), surface tension (intermolecular forces and capillary with Jurin law). Topic 2: STATIC FLUID. Fluid pressure. Height or pressure load. Fundamental equation of hydrostatics, Pascal's theorem. Communicating vessels. Absolute pressure and gauge pressure and pressure measuring devices: barometer and manometer. Hydrostatic forces on flat submerged surfaces: dams and gates Floatation and stability: Archimedean Principle. |
Block II. FLUID DYNAMICS | Unit 3: KINEMATICS OF FLUIDS: Description of current lines, trajectories. Fluid Flow Fundamentals Flow and instrumentation concept. Continuity equation. Viscosity and Newton's Law for viscosity. Definition of ideal / real fluids. Topic 4: DYNAMIC FLUID: Bernoulli equation in ideal fluids: deduction and limitations in its use in flows Energy terms of Bernoulli's equation. Scheme of energy lines in ideal fluids Applications of the Bernoulli equation: Torricelli's theorem, Mariotte bottle, siphon, infiltrometer and Magnus effect. Flow measurement: Pitot tube, Prandtl tube, Venturi tube. Topic 5: MECHANICAL FLUID ANALYSIS: Reynolds number. Laminar or turbulent flow. Distribution od speed. Friction. Stokes' law. Terminal velocity. Boundary layer: concept and definition. Shape resistances. Hagen-Poiseuille equation. Topic 6: FLOW AND LOAD LOSSES IN HYDRAULIC SYSTEMS Bernoulli equation for real fluids. Head loss in facilities. Losses or gains corresponding to pumps or turbines. Power and performance. Hydraulic resistors placed in series or parallel. Calculation of primary losses.
