Learning outcomes of the course unit
Knowledge and understanding: by means of frontal lessons, the student acquires the method and knowledge required to describe the fluid flow in the pipes, to understand the design and installation criteria for the distribution networks of the main utilities.Applying knowledge and understanding: Through practical classroom exercises connected to some important topics, students learn how to apply the acquired knowledge in a real context of design, as well as in multidisciplinary or non-familiar areas.The possibility to voluntary participate to an interdisciplinary project in a group enables the student to extend and apply on a small scale the theoretical knowledge of the design and implementation of a utility plants.Making judgements: The student must be able to understand and critically evaluate the main utility plants; by means of acquired knowledge, he has to be able to analyze existing plants, to evaluate their performance and adequacy, to elaborate numerical data and to support decisions about the plant itself. In particular, he must have acquired the ability to independently assess and design a utility plant (source or generator, distribution network) that meets the requirements imposed by the connected machines.Communication skills: Through the front lessons, the assistance of the teacher and the voluntary group project, the student acquires the specific vocabulary inherent to the utility plants. At the end of the course, the student is expected to be able to communicate the main contents of the course, both written and orally, such as ideas, engineering issues and related solutions. The student must communicate his knowledge through appropriate tools, so numerical problems are solved using common methods in the industry such as tables, diagrams, flow charts, and numerical spreadsheets.Learning skills: The student who has attended the course will be able to deepen his knowledge of utility plants through the autonomous consultation of specialized books, scientific or divulgative journals, even outside the topics explained during lectures.
There are no mandatory propedeuticities.
Course contents summary
The course aims to provide the students with the general criteria for designing and realizing the main utility plants for the production facilities. Therefore, the contents proposed during the course include in the first part of the course the analysis of fluid flow in pipes, an overview of the elements that compose the piping network, as well as the criteria to adopt for piping protection and installation. In the second part of the course, the main utility plants, such as water, steam and compressed air, are described and analyzed in detail.
Chapter 1. FLUID DYNAMIC CIRCUIT: ANALYSIS AND DESIGN
Chapter 2. THE PIPING
Chapter 3. INSTALLATION AND PROTECTION OF UTILITY PLANTS
Chapter 4. HOT WATER PLANTS
Chapter 5. STEAM PLANTS
Chapter 6. COMPRESSED AIR PLANTS
Chapter 7. REFRIGERATION PLANTS
The notes of the lectures and exercises, and all the supporting material (drawings, plant schemes, Excel spreadsheets, .MPG and .MP3 media) are available to students and shared in a Google Drive folder. To be invited please send a mail to the professor firstname.lastname@example.org including "Shared folder SGI Drive" in the Object field.In addition to the shared material, the student can personally study some of the topics discussed during the course in the following books:A. Monte, "Elementi di impianti industrali"M. Gentilini, "Impianti meccanici"Andreini, Pierini, "Generatori di vapore di media e piccola potenza"A. Pareschi, "Impianti meccanici per l'industria"
The course counts 9 CFUs (one CFU, University Credits equals one ECTS credit and represents the workload of a student during educational activities aimed at passing the exams), which corresponds to 72 hours of lectures. The didactic activities are composed of frontal lessons alternating with exercises. During the frontal lessons, the course topics are proposed from the theoretical and design point of view.During classroom exercises students are allowed to bring their own computers and tablets, and they will apply theoretical knowledge to an exercise, a real case study, or a project.The possibility to voluntary work on a common project (groups of 3 or 4 people maximum) allows the student to extend and apply on a small-scale case study the theoretical knowledge of design and implementation of a utility plant. Students applying to the project work are exempted from the written exam questions that relate to the contents of Chapters 1, 2, 3, 4 of the course.If conditions are favorable, an optional visit to the thermal power station of the "Campus" facility is organized in order to observe the application of the knowledge to a real plant.The slides and notes used to support the lessons will be uploaded to the Elly Platform. Notes, slides, spreadsheets, tables, and all shared material are part of the didactic material. For non-attending students, it is important to stay up-to-date on the course through the Elly platform, the only communication tool used for direct teacher / student contact.On this platform, day by day, the topics discussed in the lesson are pointed out and registered, providing the students with an index of the contents for the final exam.
Assessment methods and criteria
Verification of the knowledge takes place through a written test based on open questions, lasting 2 hours. The test usually consists of 6/7 questions that may relate to theoretical content, demonstrations, and exercises that have been done during the course; theoretical demonstrations and treatments have a weight of 1.0; Plant design and technical drawings weight 1.5; Exercises weight 1.8. The final vote is calculated by assigning a mark in the range 0-30 for each question and then performing the weighted average of the individual evaluations, with final ceiling to the next unit; the test is exceeded if it reaches a score of at least 18 points. “30 cum laude” is given to students who achieve the highest score on each item and use precise vocabulary.Students performing optional project work are exempted from written exam questions that relate to the contents of chapters 1, 2, 3, 4 of the course (normally 3 or 4 questions).The course, with a weight of 6 CFUs, is provided as an optional course to the students of Industrial Engineering. They will benefit of a reduced examination program; in particular they will not be required to study demonstrations, technical drawings and resolution of exercises; thus they will have a specially tailored written test.
