Content
1. Lab sessions (supervised activity):
- The total number of sessions per student will be 22, in morning hours (check the timetables of the degree in the web site of the School of Engineering).
- Lab sessions are not consecutive. The organization of these sessions will be explained at the beginning of the course taking into account the different groups.
- There is a first session of compulsory attendance (data that will be announced via Moodle) where the schedule of the lab sessions, the distribution of the students in turns and groups will be presented.
- 21 lab sessions for the realization of the following practices:
Centrifugal compressor
Centrifugal pump
Circulation by fixed bed / fluidization
Pressure drop in accidents
Heat Exchangers
Heat transfer by convection
Homogeneous kinetics
Determination of reaction heat
Heterogeneous kinetics
Determination of the effective diffusion within a particle
2. Practical reports
Preparation of reports based on the data obtained in the lab. The analysis of observations carried out in the laboratory and of the results obtained is even more important than the experimental part of the subject. It is necessary to demonstrate that each practice has been understood trough the comments and analysis of the results obtained.
Methodology
Being an eminently practical subject, attendance at the laboratory sessions is COMPULSORY.
Depending on the number of students, the academic calendar and the number of experimental facilities, the students will be divided into slots, up to a maximum of 3, and each slot in work groups, up to a maximum of 14.
The presentation session is common to all slots and attendance mandatory. In this session the different slots and working groups will be established.
The different slots and working groups will attend to the lab alternately: In case, for example, of the existence of 3 slots, slot 1 will attend lab sessions for X days, followed by X days by slot 2 and X days by slot 3; then again slot 1 for Y days, slot 2, Y days too and slot 3, another Y days and so on till the completion of the lab sessions.
Scheduling of presentation session and lab sessions will be published in Aula Moodle as well as deadlnes for the delivery of practical reports.
Students must wear their own lab coat, a note-book and the practice script previously studied. Contact lenses are not allowed.
The general rules of security in the lab can be found in Aula Moodle.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment
Attitude towards lab work: 15%
Global exam: 15%
Practical reports: 70%
a) Evaluation activities
Attendance at the lab sessions is obligatory. Every day of non-attendance discount 0.15 points out of 1.5 from the attitude in the lab mark. In addition, the mark of the practical report corresponding to the lab session to which the student has not attended will be reduced by 30%. The laboratory mark, apart from the attendance, also takes into account the attitude towards the subject (behaviour in the lab, reading the scripts and preparing the practice prior to the lab session, copy in laboratory reports or exam, etc.).
To pass the subject, in addition to attending to lab sessions and presenting the report of all the practices on the corresponding day, students must reach a minimum average mark of 60% of the reports, 60% of the grade "Attitude in the lab” and 30% in the global exam. The weighted average of these marks must be above 5 out of 10. If the minimum mark is not reached in any of these three concepts, but the weighted average of the notes obtained is above 5 out of 10, the final mark of the subject will be 4 out of 10. In the rest of the cases, it will be the average mark that has been obtained. When the mark on Attitude in the lab does not reach 60% for reasons of attendance, the final grade of the subject will be Non-Evaluable.
In order to be able to attend to the global exam, 60% of the report mark and 60% of the attitude mark must be previously reached.
b) Schedule of evaluation activities
The date of the global exam will be given on the presentation session and will be published in Aula Moodle and on the School of Engineering website. The schedule of the different lab sessions will also be given in the presentation session and published in Aula Moodle.
c) Resit process
In accordance with the School of Engineering rules regarding the eminently practical subjects, no resit exams will be scheduled.
d) Review of practical reports and global exam
For the review of the results of the practical reports and global exam, data and place will be determined within the 10 working days following the publication of the marks.
e) Qualifications
Students not attending 30% of the lab sessions or more will be deemed not eligible.
To award a student with an Honors Qualification, apart from the threshold mark stablished in UAB Regulations, different aspects of the student work and attitude will be considered: proactivity towards the subject, the manual ability in the laboratory, the understanding of the basics of the practices and its relationship with other subjects and the fluidity, reliability and reasoning capacity in situations such as those posed by practices.
f) Irregularities by the student, copy and plagiarism
Without prejudice to other disciplinary measures that are deemed appropriate, and in accordance with the current academic regulations, the irregularities committed by the student that can lead to a variation of the qualification of an act of self- evaluation will be penalised. Therefore, copying, plagiarizing, cheating, etc. a report on lab practices or any other activity of evaluation will imply a zero (0) in the Attitude towards work in the lab and, consequently, to fail the subject.
g) Evaluation of repeating students
Repeating students have two possibilities:
• Pursue the entire subject again as if they were enrolled for the first time. This possibility is mandatory for students repeating as a consequence of copying, plagiarizing, etc.
• Repeat only the reports of those practices that, in the previous year, were rated with a score of less than 6. They will not have to go to the laboratory but to prepare the practical reports using lab data obtained during the previous year (20-21). To pass the subject, students must obtain at least 6 out of 10from each of the reports and a minimum of 5 out of 10 from the global exam. The calculation of the mark will be based on: 70% average of the mark of all the reports and 30% the mark of the exam. In any case, by this means, students will be candidate for an Honors Qualification.
