0.- Description of the subject
The subject Mass and Energy balances has a direct link with those that make up the module "Fundamentals" in the Master in Environmental Engineering as well as other materials which use mass and energy balances as a tool: "Wastewater treatment technologies"," Operation of WWTP and ETAP "," Management and treatment of waste, "Atmospheric environment and reduction of emissions," "Clean technologies" and "Eco-design of processes and products."

1.- Objectives
This subject has as main objective to acquire general knowledge of major environmental problems and possible solutions in the field of prevention and end of pipe treatment. In both cases it is essential to an understanding of mass and energy flows of products/processes/ services involved; requirement for decision-making process of technological solutions (improvements in the design, definition of operating parameters, etc..), economic (increasing the efficiency and productivity of the systems), environmental (emissions reduction strategies etc..) and social (definition of health and safety aspects at work, reduction of harmful effects to workers, etc.).
The contents are developed in the course related to those of the subject descriptotr in the curriculum of the Master in Environmental Engineering: "Mass balance. Total energy balance and mechanics. Application of fluid flow and water system ". The program is divided in three basic themes, which are listed below:
Unit 1. Mass balances. General formulation of the mass balance. Equation of macroscopic mass balance. Mass balances in systems with and without chemical reaction.
Unit 2. Energy balances. Equation of macroscopic energy balance. Energy balances in systems with and without chemical reaction.
Unit 3. Fluid flow. Mechanical energy balances: Bernoulli equation. Incompressible fluid flow: Fanning equation. Impulsion of fluids by pipelines. Pumps and compressors.
Specific objectives
The mass and energy balances consist of the quantification of input and output flows to a given system. This system can be as simple as an air conditioner, or as complex as an ecosystem. The accomplishment of the balance involves solving systems of linear or nonlinear equations, where from a limited number of data we have to make different "balances" or "equations" between the various flow lines, leading to obtain the values of the variables problem of the "system."
The third unit has as main objective that students know the fundamentals of fluid mechanics, particularly the Bernoulli equation, with the introduction of the concepts "pressure drop" and "work" indicating as the former can be calculated in simple and complex pipeline systems via Fanning equation. Finally, we will address the main types of pumps and compressors, making a series of problems illustrating the use of pumping systems for fluid transport in pipes.
The activities developed by the students are:
A series of problem sets will be delivered, of which a limited number will be solved in the classroom. In addition, students will propose some of the problems for their resolution in the classroom and as individual work (this activity must be conducted in groups). In the tutorials, compulsory and individualized, these problems will be analyzed and evaluated.
Reading of two book chapters (individual activity):

Basic
• CB6. Knowledge and understanding that provide a basis or opportunity for originality in developing and / or applying ideas, often in a research context
• CB7. To apply the broader (or multidisciplinary) acquired knowledge and ability to solve problems in new or unfamiliar environments within contexts related to their field of study
• CB8. To integrate knowledge and handle complexity and formulate judgments based on information that was incomplete or limited, include reflecting on social and ethical responsibilities linked to the application of their knowledge and judgments
• CB9. To communicate their conclusions and the knowledge and rationale underpinning to specialists and non-specialists in a clear and unambiguous
• CB10. Capacity for independent learning
General
• GO1. To identify and develop environmental
Specific
• E11. To have a comprehensive understanding of environmental problems
• E12. To relate the laws of the different areas to achieve sustainability
• E14. To understand their technologies, tools and techniques in the field of environmental engineering
• E42. Commitment with environmental protection and sustainable development

The methodology of the subject is based fundamentally on case studies, with lectures and face-to-face seminars. These classes will be supported by the use of presentations in MS Power-Point and MS Excel. A maximum of 10% of the hours may be taught telematically to encourage the participation of lecturers from other universities. The Learning Management System and MS Teams applications will be used as communication tools with students.
Relationship between teaching methodologies and the development of competences:
• Lectures in classroom: CB6, CB7, E11, E12, E42
• Seminars: CB6, CB7, CB8, CB10, G01, E11, E12, E14, E43, E46, E47
• Group tutorials: CB9, E11, E42, E47
Evaluation activities:
• Problem (team work): 50%
• Overview of book chapters required reading: 10%
• Exam: 40%.
The student has to obtain a minimum of 3 out of 10 in the exam to be considered for the balanced score. The exam will consist in the resolution of one case study. It can use the spreadsheet carried out in class as well as tables and supplementary material given in the USC Learning Management System.
Skills assessment:
• Problem: CB6, CB7, CB10, G01, E11, E12, E14, E43, E46, E47
• Overview: CB8, CB9, E11, E42, E47
• Exam: CB7, E46
The subject has a workload of 4.5 ECTS, an ECTS credit corresponds to 25 hours of total work, which are allocated as follows:
Activity Classroom hours Factor Personal work TOTAL
Theory 10.0* 1.25 12.5 22.5
Seminars 20.0 1.75 35.0 55.0
Practicals 3.0 1.65 5.0 8.0
Compulsory tutorials 3.0 3.0 9.0 12.0
Exam 3.0 4.0 12.0 15.0
TOTAL 39.0 - 73.5 112.5
Students enrolled in this subject must have basic knowledge on linear algebra and mathematical analysis, chemistry and physics. They must also possess a wide knowledge of Excel.
It is also advisable that students have a number of additional knowledge such as English language proficiency at level of reading and knowledge of user-level applications (primarily Excel)
The laptop is used in an important way in this subject, since many of the case studies require computer applications as a support element.
The language of the subject will be Spanish in line with the strategic decision of the Master that defined as a fundamental target the recruitment of students from outside the autonomous community.
