Presentation
Its field of action is directed to general engineering by appealing and developing the knowledge acquired in Physics and Fluid Mechanics to explain the basic concepts of Hydraulics in view of applications to concrete situations The main concepts are presented to understand, describe and calculate the most common phenomena that arise in practical applications working in key policy areas of hydraulic phenomena seeking understanding of hydrostatic, the hydraulic load concept through to the hydrodynamics and the analysis of different types of flow taking into account the determination of pressure loss with use of dimensional analysis and common empirical formulas covering knowledge basic hydraulic machines. The UC is relevant because it transmits knowledge indispensable when the diagnostic situations, the design, operation and management of hydraulic systems.

Syllabus
Syllabus
Physical properties of the fluids: physical constants; dimensional analysis. Theoretical bases of hydraulics: kinematics, dynamics, flow energy. Hydrostatic: fundamental equations, pressure distribution; impulsion. Hydrodynamics: Flows under pressure, by gravity and by pumping. Continuous load losses: general expression, Reynolds number, absolute and relative roughness, resistance factor, Moody diagram, empirical formulas.Localized load losses: general expression, equivalent length of conduct, calculation of localized losses in different types of singularities. Power and piezometric lines: trace, position of the piezometric in relation to the conduit. Pumps and Turbines. Flows with free surface: distribution of pressures and velocities, uniform flow height, specific energy, flow capacity curve, elements of the critical state.

Teaching methodologies and assessment
Teaching methodologies and assessment
The teaching methodology is based on two components: theoretical and practical classes, in which the theoretical lessons are put into practice. The rating is from 0 to 20 values. Continuous evaluation : The evaluation of the practice consists in the resolution / discussion of exercises of the various programmatic contents. The final grade will be given by the weighted average of the practice (25%) and the tests (75%). Final Exam : Classification of 10 or higher.
