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
Butera: A written multiple choice test [10 questions (1.5 points each) + 1 exercise (5 points)] and an oral exam. The student accesses to the oral exam if the written exam is passed with a grade >12.
Camporeale: A written multiple choice test [15 questions (1.5 points each) + 5 exercises (1.5 points each)] + 1 open question. The oral exam is facultative. The open question is assessed only if the test is passed with a grade > 18/30. The overall grade is 70% from the test and 30% from the open question.
