Prerequisites:

The required background includes a basic knowledge of Mathematical Analysis 1 and 2, Linear algebra and geometry, and Physics 1 
Target skills and knowledge:

Basic elements of fluid mechanics, with particular reference to incompressible Newtonian fluids.
Specifically, expected knowledge and skills are:
1. Knowledge of the physical properties of fluids.
2. Knowledge of fundamental conservation principles (mass, momentum, energy).
3. Knowledge of simplified models (e.g., hydrostatic, perfect fluid) along with underlying approximations and limitations of use.
4. Identifying appropriate basic assumptions to face specific problems.
5. Solving problems and exercises by properly applying the acquired theoretical tools. 
Examination methods:

Written examination. Exercises (hydrostatic and steady fluid dynamics) and theory (three open questions on topics covered by the program).
The exercise exam will permit you to use your notes (one page with relevant formulas) and a calculator. The exercise exam will not present you with routine problems, in order to probe for mastery of the underlying material and concepts, and for skill in finding solutions in the simplest possible realistic terms.
The theory exam will not permit you to use any kind of material. In your answers, you are generally required to enunciate the basic hypotheses, the logical steps and the justifications necessary to support the conclusions. The answer to the third question also requires a description as complete and exhaustive as possible of the problem. 
Assessment criteria:

1. Correctness of developments and of calculations
2. Completeness and orderliness of essay
3. Clarity of exposition
4. Rigour in using the technical terminology
The level of correspondence to these criteria will determine the final mark. 
Course unit contents:

Definitions and general properties of fluids. Equilibrium of fluids at rest; forces on immersed surfaces. Kinematics of fluids; Lagrangian and Eulerian approaches, Reynolds transport theorem. Principles of conservation of mass and momentum, in integral and differential form. Fluid dynamics: constitutive relation for Newtonian viscous fluids; NavierStokes' equations. Flow at high Reynolds numbers: definition of perfect fluid; Euler's equations; Bernoulli theorem and relevant applications. Potential flows (basics). Vorticity dynamics (basics). Laminar flows: motion between parallel planes and in pipes. Turbulent flows; Reynolds' equations, turbulent flow in pipes. Flow resistance in pipes, continuous and localized energy dissipations. 
Planned learning activities and teaching methods:

Frontal teaching (on the blackboard) and practical exercises.
Theoretical lectures are followed by practical examples.
The explanation of some topics is supported by multimedia material. 
Additional notes about suggested reading:

Lesson notes (also available on the Moodle platform) and books for deepening of personal knowledge. 
Textbooks (and optional supplementary readings)
