Subject fundamentals
The aim of the course is to give the basic knowledge of fluid properties of compressible and incompressible fluids and their behavior. Elementary problems are given such as computation of forces in static and dynamic conditions and analysis of fluid motion in pressurized pipelines will be discussed.
Expected learning outcomes
Knowledge of the properties of compressible and incompressible fluids.
Knowledge of the functioning of instruments for measuring static, kinematic and dynamic properties of fluids
Knowledge of problems related to turbulent flows
Knowledge of design methods for pressurized pipes in permanent regime
Ability to perform the dimensioning of pipelines
Ability to calculate fluid forces on surfaces.
Prerequisites / Assumed knowledge
Knowledge of calculus (differential equations, integrals) and the concepts of physics relating to mechanics

Assessment and grading criteria
The assessment will be composed of a written test and an oral evaluation. The written test will verify the student ability to solve simple fluid mechanics problems, and the oral evaluation will assess the understanding of the theoretical concepts of the course.
The written test will include 10 multiple-choice questions (1.5 points each) a one exercise (5 points), with a maximum score of 20 points. The written exam is passed with a minimum of 10 points. The oral exam will be based on one theoretical question, with a maximum of 10 points.
