Prerequisites
Convenient to have studied the subject 102405 Mass and energy balance in chemical engineering.
Objectives and Contextualisation
The main objective is to select and design equipment based on the circulation of fluids existing in any industrial plant.
Other more specific objectives:
• Apply the mechanical energy balance to the study of the fluid flow.
• Study and dimension the equipment for the transport of incompressible fluids.
• Know the necessary instrumentation or based on the fluid flow.
• Expand the application of the mechanical energy balance to the circulation of compressible fluids.
• Understand the foundation of unit operations based on the fluid flow.
• Design the equipment of the most relevant unit operations.
Competences
- Communication
- Demonstrate knowledge of the different reaction, separation and processing operations for materials, and transport and circulation of fluids involved in the industrial processes of chemical engineering.
- Develop personal attitude.
- Develop personal work habits.
- Develop thinking habits.
- Objectively compare and select different technical options for chemical processes.
- Understand and apply the basic principles on which chemical engineering is founded, and more precisely: balances of matter, energy and thermodynamic momentum, phase equilibrium and kinetic chemical equilibrium of the physical processes of matter, energy and momentum transfer, and kinetics of chemical reactions
Learning Outcomes
- Communicate efficiently, orally and in writing, knowledge, results and skills, both professionally and to non-expert audiences.
- Describe the operations for the transport and circulation of fluids involved in the industrial processes of chemical engineering.
- Develop a capacity for analysis, synthesis and prospection.
- Develop curiosity and creativity.
- Develop independent learning strategies.
- Efficiently use ICT for the communication and transmission of ideas and results.
- Identify, analyse and resolve mechanical energy and matter balances.
- Manage available time and resources. Work in an organised manner.
- Objectively compare and select different technical alternatives for fluid circulation systems.
- Work autonomously.

Methodology
The fundamentals will be introduced by videos and teaching material.
Class will be dedicated to apply concepts to case studies and to solve questions.
Concepts will be applied also to solve selected problems.
Search of information related to the description of equipment by the students.
During lectures students will complete a numerical project of fluid flow installation.
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
The subject is divided into two parts: part A (block 1 and 2) and part B (block 3 and 4).
a) The evaluation activities and the percentage of the final mark are calculated according to the expression:
Final mark = 0.25 * Exam A + 0.25 * Exam B + 0.20 Numerical project + 0.10 * multiple choose exam + 0.10 solved problems + 0.10 * descriptive report
To pass the Exams A and the B, 50% of the mark must be achieved, on the contrary the exam must be repeated.
Each exam will contain a part of theory and a part of problems. Only the part of problems will be scored if you get a grade greater than or equal to 40% in the theory part.
The team description report is in groups that the teacher makes of 2-3 people.
Project work consists of designing a simple installation for a fluid flow circulation. The work is done mainly in class and cooperatively in teams established by the teacher.
b) Programming of the evaluation activities
Equipment description works will be delivered during week 3 and will be corrected as the theory advances.
Multiple choose exams with questions about the equipment will be performed through the Moodle classroom a week after uploading the description work of the corresponding teams.
During the semester it will be requested that some resolved problems be submitted that will be scored in the co-evaluation system and for the teacher.
c) Recovery process
No restricions for the recovery exams.
d) Procedure for the review of qualifications
For each Exam and retrieval, thedate, time and place will be indicated when the notes are published.
The regulations of the UAB indicate that Honor Grade only be awarded to students who have obtained a final grade of 9.00 or more. It can be granted up to 5% of Honor Grade of the total number of students enrolled.
To obtain a HG it is essential to obtain a good qualification in the 1st version of the numerical project and to carry out a task of leader in the work team.
f) Iregularities by the student, copy and plagiarism.
Without prejudice to other disciplinary measures considered appropriate, the irregularities committed by the student that can lead to a variation in the rating of an evaluation act will be qualified with a zero. Therefore, copying, plagiarizing, cheating, copying, etc. In any of the assessment activities it will result in fail it with a zero. Assessment activities qualified in this way and by this procedure will not be recoverable. If it is necessary to pass any of these assessment activities to pass the subject, this subject will be suspended directly, without opportunity to recover it in the same course.
The copy may be detected during the exam, but especially during the correction, so that actvity with equal versions will be annulled.
In cooperative work, it is recommended to denounce "jetas" and "mantas" that hurt their development. As of the complaints, measures that may entail the expulsion of the group and therefore the impossibility of passing the subject during the same course will be pending.
h) Evaluation of the repeaters.
No activity score of previous course will be maintained.
The simplified assessment consists in
Final grade = 0.3 * A + 0.3 exam* B + 0.25 numerical project + 0.15 * multiple choose exams.
