To know the fundamentals of Fluid Mechanics, including the characterization of fluids and its differences comparing to solids. To know the fundamental laws of fluids at rest, and its interaction with confining surfaces.
To learn the principles of mass, momentum and energy conservation apllied to fluid flows, both in its integral and differential formulations. To learn and to apply the dimentional analysis and similitude principles, regarding the experimental study of Fluid Mechanics.

2. Fluid Statics Balance of forces in a fluid at rest Hydrostatic equation Manometry Absolute pressure and relative pressure Atmospheric pressure Pressure measurement Forces on immersed surfaces Centre of pressure Buoyancy
3. Fluid Kinematics Concept of flow Properties of velocity fields Streamlines and trajectories Visualization and techniques of flow visualization Langrangian and Eulerian description Concept of discharge and average velocity
4. Fluid Dynamics (non-viscous fluids) Newton’s 2nd law applied to a fluid particle Integration in a flow line Euler’s and Bernoulli’s equations How to apply Bernoulli’s equation Dynamic pressure and total pressure Stagnation point Energy line Piezometric head Pitot and Prandtl tubes. Velocity measurement Velocity profiles and average velocity profiles Newton’s second law along the streamline direction Pressure in a free-jet-nozzle
5. Fluid Dynamics (integral formulation) Reynolds’ transport theorem Equation of mass conservation Examples Conservation of mass equation, linear equation of motion (linear and angular) and energy equation Examples
6. Fluid Dynamics (differential formulation) Mass conservation and quantity of movement (Navier Stokes’ equations) Frontier conditions Examples Couete and Hagen-Poiseuille flow
7. Dimensional analysis and similarity Dimensionless: functional dependence Buckingham’s PI theorem Dimensionless: selection of variables and reference dimensions The unique nature of Pi Interpretation of the most common dimensionless groups in Fluid Mechanics Similarity and modulation Conditions of similarity Elementary dimensionless equations in Fluid Mechanics
The course is organized into three theoretical-practical classes of 1.5h per week. In each class theoretical concepts are exposed and followed by the application of practical cases.

The student cannot exceed the absence limit allowed (25% of the practical classes), according to the current rules.
Assessment is through 3 elements of evaluation:
1) a test in the moodle platform with a weight of 20% for the final mark;
2) a second test in the moodle platform with a weight of 20% for the final mark;
3) a final written exam with a weight of 60% for the final mark.
Resit exam has two parts: a moodle test with a weight of 40% for the final mark and a written exam with a weight of 60%.
Same format as the resit exam,
Classification improvement exam will take place at the same time as the resit exam.
