1. Basic Information

1.1. Objectives of the subject

The subject Machines and Fluid Installations focuses on the calculation and design of fluid installations and their active elements: pumps and turbines

The hydraulic design of a fluid machine consists of the determination of the best constructive form that it should have to provide/receive the specified energy to/from the fluid. For this purpose, the influence of the internal geometry of the machine on the fluid/machine interaction energy is described with a simplified one-dimensional theory.

The calculation of installations requires the use of optimization criteria with respect to specified criteria that allow the design of an energy efficient installation. Special emphasis will be placed on pumping installations, which are the most common in industrial engineering practice.

These approaches and objectives are aligned with the following Sustainable Development Goals (SDGs) of the United Nations Agenda 2030 (https://www.un.org/sustainabledevelopment/es/), in such a way that the acquisition of the learning results of the subject provides training and competence to contribute to some extent to their achievement: Goal 2: To end hunger, achieve food security and improved nutrition, and promote sustainable agriculture. Objective 2.3 By 2030, double the agricultural productivity and incomes of small-scale food producers, including women, indigenous peoples, family farmers, pastoralists and fishers, through secure and equitable access to land, other production resources and inputs, knowledge, financial services, markets and opportunities for value addition and off-farm employment

Goal 6. Ensure the Availability and Sustainable Management of Water and Sanitation for All.

Objective 6.4 By 2030, significantly increase the efficient use of water resources in all sectors, and ensure sustainability of freshwater withdrawals and supplies to address water scarcity and significantly reduce the number of people suffering from water scarcity

Goal 11. Making cities and human settlements inclusive, safe, resilient and sustainable.

Objective 11.1 By 2030, ensure access to adequate, safe and affordable housing and basic services for all people and improve slums.

Objective 11.6 By 2030, reduce the per capita negative environmental impact of cities, including paying particular attention to air quality and municipal and other waste management

1.2. Context and meaning of the subject in the degree syllabus

The subject Fluid Machines and Installations is an integral part of the group of compulsory subjects within the industrial branch. This is a subject of 6 ETCS that is taught in the first semester of the third year. It is constituent material of a fundamental part of industrial engineering such as the transport and distribution of fluids, as well as the interaction of these with the mobile and fixed elements in power generation machines.

1.3. Recommendations to take the subject.

It is recommended to have studied and understood Fluid Mechanics. There are concepts of that subject used profusely in the development of the present one. It is advisable that students adopt a system of continuous study and that they make frequent use of the tutorials with the teacher to solve those doubts that will surely arise in the learning of the subject.

2. Learning results

2.1- Competencies

Specific competencies:

C35: Ability to apply knowledge of fluid mechanics and the calculation, design, and testing of systems and 

fluid-mechanical machines.

Generic competencies:

C4: Ability to solve problems and make decisions with initiative, creativity and critical thinking.

C6: Ability to use engineering techniques, skills and tools necessary for engineering practice.

C10: Ability to learn continuously and develop autonomous learning strategies.

2.2- Learning Results

1. Understands the operation and applications of fluid machines

2. Is capable of dimensioning a fluid machine subject to general technical specifications.

3. It has the ability to size a fluid installation.

4. Applies efficiency criteria in the design of an installation.

5. Knows how to design protocols for the operation and exploitation of facilities based on efficiency, economy and reliability criteria.

2.3- Importance of learning results

G graduates in Mechanical Engineering will face in their professional life multiple situations in which in one way or another they will have to work with facilities that transfer fluids. This subject is the key to ensure that they are designed with basic energy efficiency criteria.

Topic 6. Operation of pumping and ventilation lines. Fluid distribution networks.

 Topic 7. Flow regulation in pumping and ventilation lines.

Topic 8. Cavitation. Effects of cavitation in turbomachines. Similarity in cavitation.

4. Academic activities

4.1- General methodological presentation.

1. Lectures, given to the whole group, in which the teacher will explain the theory of the subject and will solve problems relevant to the calculation of installations and the determination of the geometry of pumps/turbines.

2. Laboratory practices. These practices are highly recommended for a better understanding of the subject because they show in real operation elements whose calculation is done on the blackboard.

3. Tutorials related to any subject of the subject

4.2- Learning activities.

Attendance to all learning activities is of special relevance to acquire the competencies of the subject.

Master classes. They will be developed at a rate of four hours per week, until completing the 50 hours that we consider opportune to dedicate to complete the syllabus.

Laboratory practices. Five sessions will be held at a rate of two hours per session with subgroups of three/four people Study and personal work. This non-face-to- face part is valued at about 90 hours, necessary for the study of theory, problem solving and script revision

Tutoring. Each teacher will publish a schedule for student attention throughout the term.

4.3- Planning of learning activities and calendar of key dates

The master classes of theory and problems are given in the timetable established by the centre, as well as the hours assigned to practical classes

The presentation of the papers will take place on the last day of class of the subject The dates and times of the subject can be found at on EINA's website :http://eina.unizar.es

Likewise, students will have at the beginning of the term the dates and places of the exams required to pass this subject.

4.4- Recommended bibliography and resources

The updated bibliography can be found in the BR of the BUZ

5. Assessment system

The evaluation will be carried out by means of a global written test in the two official exams established for this purpose by EINA

The examination will consist of four parts:

- Problem #1 (30% of the final grade)

- Problem #2 (30%)

- Theory (20%)

- Questions on laboratory practices (20%)

A minimum of 3 points out of 10 will be required in each of the above mentioned parts of the exam (Problem 1, Problem 2, Theory and Practical) in order to be averaged.

The student has the option of doing a subject assignment. If they choose to do so, the weight of the overall exam in the final grade will become 95% (the exam grade is multiplied by 0.95) and the remaining 5% will come from the evaluation of the work.
