OVERVIEW

The teaching provides the basis for the study of fluids both in motion and at rest. By the end of the teaching, the student will be able to solve simple problems concerning the action of a fluid on a body contained within it and problems related to simple hydraulic systems.

AIMS AND CONTENT

LEARNING OUTCOMES

The course aims to provide the student with basic knowledge on the motion of fluids. Such knowledge will be applied to the solution of hydrodynamic problems in global form and to the design and verification of simple hydraulic systems.

AIMS AND LEARNING OUTCOMES

On completion of the course, the student will have acquired knowledge that will enable him or her to:

•     calculate the action of a stationary fluid, with respect to both inertial and noninertial reference systems, on surfaces and bodies within it
•     solve problems related to simple hydraulic systems and networks
•     use dimensional analysis to design laboratory measurements
•     use principles formulated in global form to calculate of the action of a fluid in motion on surfaces and bodies within it.

PREREQUISITES

Have a solid understanding of the topics covered in the courses GENERAL PHYSICS and MATHEMATICAL ANALYSIS I.

TEACHING METHODS

The teaching is divided into lectures and tutorials, both conducted by the teacher. In the lectures, the theoretical part of the teaching will be exposed. The theoretical part will be supplemented with examples and exercises, carried out in the classroom by students under the supervision of the teacher.

The exercises will consist of classroom correction of exercises, proposed beforehand, which the student will have done independently at home

Students with valid certifications for Specific Learning Disorders (SLDs), disabilities or other educational needs are invited to contact the teacher and the School's disability liaison at the beginning of teaching to agree on possible teaching arrangements that, while respecting the teaching objectives, take into account individual learning patterns.

EXAMS

EXAM DESCRIPTION

Participation in the examination is subject to the fulfillment of the required propedeuticities.

The exam consists of a first written part (1 exercise) and an oral part.

The written test will be corrected immediately after its completion in the presence of the student. The discussion of the written test is part of the oral part.

To be eligible for the oral part, it is necessary to have passed the written test.

The oral part, which consists of two questions on the topics covered in the module, will take place immediately after the written test has been corrected and passed.

ASSESSMENT METHODS

The written part of the verification is designed to ascertain that the student has acquired the techniques for solving the problems described in the training objectives. The oral part of the verification is designed to ascertain the degree of understanding of the techniques used and their scientific foundations within the subject matter, clarity of reasoning, competence in the use of scientific terms, and knowledge and degree of depth of the topics covered in the module
