Course description

ducational objectives
Knowledge and understanding:
During the course the student will learn the basics of
Fluid mechanics and will develop the ability to understand and analyze
critically the physical reason for phenomena concerning still or in fluids
motion in natural or artificial systems.
Skills:
The student will gain the ability to apply the basics
of hydraulics to elementary problems typical of civil engineering e
environmental.
Judgment autonomy:
The student will acquire the basic tools and develop an ability
useful critiques to independently analyze and deal with problems
elementary hydraulics.

Prerequisites

Having taken the Physics exam I. Having attended the courses of Mathematical Analysis,
Geometry, and rational mechanics.

Teaching Methods

The course is mainly divided into lectures
for the presentation of theoretical aspects and in-depth themes.
Problems of interest are addressed numerically during the exercises
application. A test is performed on static exercises.

Learning assessment

The exam consists of an oral test, preceded by a written test whose
passing is a necessary condition for access to the interview, on the basis of which
the student is evaluated. The two tests can be deferred for a maximum of 3 months.
The passing of the test entitles you to the exemption of the exercise on fluid static.
