Academic Year 2023/2024 - Teacher: ANTONELLA PATTI

Expected Learning Outcomes

The aim of the course is to provide the knowledge of the transport phenomena of momentum, energy and mass, through the macroscopic and microscopic balances, in order to allow the study of the physical phenomena that take place inside of industrial processes. Finally, it will be considered simple models of the main operations of chemical engineering.

Course Structure

Lectures with numerical and practical exercises.

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.

Learning Assessment

Learning Assessment Procedures

Oral examination and test in progress. Learning assessment may also be carried out on line, should the conditions require it.

 Elements to be evaluated: Knowledge and application of properties and methods, relevance of the answers, quality of their contents, ability to connect with other topics within the program, ability to report examples, quality of technical language, and overall expressive ability.

To guarantee equal opportunities and in compliance with current laws, students can request a meeting in order to plan any compensatory and/or dispensatory measure, according to the educational goals and specific needs. In this case, it is advisable to contact the CInAP (Centre for Active and Participated Integration - Services for Disabilities and/or SLD) professor of the Department where the Degree Course is included
