Objectives
Study of the fundamentals of fluid flows. Application to pipe flow and flow over immersed bodies.
Program
1-Introduction and basic considerations
Some characteristics of fluids. Analysis of fluid behavior. Viscosity.
2-Fluid statics
Pressure at a point. Basic equation for pressure field. Manometry. Hydrostatic on a plane surface and on a curved surface.
3- Fluid Kinematics
Velocity field- Eurelian and Lagrangian descriptions. Steady and unsteady flows. Streamlines, streaklines and pathlines.
Accelaration field- material derivative. Streamline coordinates
4-The Bernoulli Equation
The Bernoulli equation along a streamline. Physical interpretation. Free jets, confined flows and flowrate measurements
5- Finite Control Volume Analysis
The Reynolds Transport Theorem. Conservation of mass- the continuity equation. Energy equation. Linear momentum equation. Examples of application.
6- Similitude, Dimensional Analysis, and Modeling.
Dimensional Analysis. Buckingham Pi Theorem. Common dimensionless groups in fluid mechanics. Modeling and similitude. Application to flow through closed conduits and flow around immersed bodies.
7- Viscous Flow in Pipes
Laminar and Turbulent flows. Poiseuille equation. Laminar flow between concentric tubes and along a wetted column. Fully turbulent flow, description and velocity profile.
8- Pipe Flow
The Moody chart. Minor losses and noncircular conduits. Single pipes and multiple pipe systems. Pipe flowrate measurements.

Eligibility for exams
To have frequency the students must have a final mark higher than five
Calculation formula of final grade
The evaluation of this course will be the following:
25% Four short tests in the classroom at the end of the most important chapters. The homework exercises will be delivered at the end of these classes
75% Final examination
The exam of the special season covers the full program taught on the discipline.
Special assessment (TE, DA, ...)
Examinations, accordingly to the calendar draw by MIEQ
