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 (topics 1 and 2) and part B (topics 3 and 4).
a) Students will have all the material on the virtual campus (videos, notes, problem collection, examples of solved problems, team description work). A self-study schedule of the different topics will be proposed with very frequent checks on the progress of the study. These will consist of:
1) test-type questions (multiple choice) about equipment description works
2) Seminar every 2-3 weeks where a problem related to the proposed sections will have to be solved
3) Carrying out a numerical work autonomously or with a tutorial
4) Block A theory exam and numerical work (1st part) and block B theory exam (2nd part)
The final grade will be calculated according to the expression:
Final grade = 15% theory exams + 60% problems + 10% test tests + 20% numerical work.
To pass block A and block B you must take 50% between theory exam and problems, otherwise you will have to recover the block not passed.
To calculate the final grade, a minimum of 30% must be obtained in each of the 4 evaluable items.
b) Scheduling of evaluation activities
The calendar of assessment activities will be published on the Virtual Campus
c) Recovery procedure
Without requirements.
d) Procedure for reviewing grades
For each test the day, hour and place will be indicated when the grades are published.
e) Qualifications
UAB regulations state that MHs can only be awarded to students who have obtained a final grade equal to or higher than 9.00. Up to 5% MH of the total number of students enrolled can be awarded.
To obtain an MH it is essential to obtain a good qualification in the 1st version of the numerical work and to exercise a task of leader in the work team.
f) Irregularities on the part of the student, copying and plagiarism.
Without prejudice to other disciplinary measures deemed appropriate, irregularities committed by the student that may lead to a variation in the grade of an assessment act will be graded with a zero. Therefore, copying, plagiarism, cheating, copying, and so on. in any of the assessment activities it will involve suspending 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 course, this course will be suspended directly, without the opportunity to retake it in the same course.
The copy can be detected during the test, but especially during the correction, so that activity with equal versions will be canceled.
In cooperative work, it is recommended to denounce “jets” and “blanket” attitudes that impair their development. Based on the complaints, measures will be taken that may lead to the expulsion of the group and therefore the impossibility of passing the course during the same year.
h) Evaluation of repeaters.
No grades are saved from any evaluation activity of previous courses.
