2.1. Learning goals
To pass this subject, the student must demonstrate the following results:
1. General learning outcomes:
- To know the fundamental concepts and laws of mechanics and thermodynamics and their application to basic problems in engineering.
- To analyze problems that integrate different aspects of physics, recognizing the various physical principles underlying a technical application, device or real system.
- To know the units, orders of magnitude of the defined physical magnitudes and solve basic engineering problems, expressing the numerical result in appropriate physical units.
- To correctly use basic methods of experimental measurement or simulation, To present and interpret the data, relating them to the appropriate physical quantities and laws.
5. – To use bibliography and/or any of the available resourses available today and to develop a clear and precise language in its explanations on questions of physics.
2. Specific learning outcomes:
- Correctly applying the fundamental equations of mechanics to various fields of physics and engineering: rigid body dynamics, oscillations, elasticity and fluid.
- Understand the meaning, usefulness and relations between magnitudes, elastic core modules and coefficients used in solids and fluids.
- Performs mass and energy balances correctly applied to fluid movements in the presence of basic devices.
- Correctly use the concepts of temperature and heat. Applies these concepts to calorimetry, expansion and heat transmission problems.
- Apply the first and second law of thermodynamics to processes, basic cycles and thermal machines.
2.2. Importance of learning goals
The learning outcome are crucial since they will provide the student with a set of knowloedges and tools required to solve simplified problems of Machanics and Thermodynamics related to the Chemical Engineering activities. They are, in turn, the starting point for further knowledge in higher year courses in the Degree.
3.1. Aims of the course
The course and its foreseen results are base don the following hypothesis and goals:
The Physics I course is focused on the fundamentals of mechanics and its applications, such as mechanical oscillation, elasticity and fluid mechanics. Also, it provides the basic principles and working hypotheses of Thermodynamics, with emphasis on the study of heat transmission and thermal machines. Being a fundamentally basic discipline, these cncepts are presented as a starting point for subsequent courses of the Chemical Engineering formation.
On the other hand, some aspects of the course, such as those related to the Laws of Conservation (e.g. momentum and energy) the vector nature of physical magnitudes; the use of Differential Calculus and the basic methodology for analyzing Laboratory data constitute an essential methodological basis for the student.
Finally, given the specific character of the Chemical Engineering discipline, those concepts of Physics will be applied to selected problems related to the Degree.
When approved on this Course, the student will have enhanced competence to:
1. SPECIFIC SKILLS:
Comprehension and control of the basic conceptus on the general laws of Mechanics, Thermodynamics, waves and fields, and their application to electromagnetism on typical problems of the field.
2. General SKILLS:
2.1 Capacity to solve problems and take decisions with initiative, creativity and critical reasoning.
2.2 Capacity to learn continuously y develop strategies for autonomous learning
4.1. Assessment tasks (description of tasks, marking system and assessment criteria)
1. Throughout the semester two short written tests, based on short questions and type test will be performed. It aims to promote the continued work of the student. In particular, this will encourage the student to better use the contents of the subject, built on previous ones.
The score on this test will involve 20% of the final grade if the student chooses to incorporate this note to your overall assessment.
Learning outcomes 1.1 and 1.3 will be evaluated.
2. At the end of the semester a test performed in the laboratory, related to both experimental methods, and the analysis of the data obtained. The contents of this test are compiled from activities conducted during the laboratory sessions.
This test will constitute 20% of the final grade. It will be eliminatory, i.e., it must be approved in order to pass the course.
Learning outcomes 1.3 and 1.4 will be evaluated.
3. A supervised practical work that will assess learning outcomes 1.1, 1.2 and 1.3 (occasionally 1.4 and 1.5) will be proposed. This part constitutes 10% of the final grade for the course.
4. At the end of the semester, according to the exam schedule center, a comprehensive written test of the subject will be taken. It will consist of two parts: one based on short questions (as in the intermediate tests) and the other consisting of numerical resolution problems.
This test, which will be between 50% and 70% of the final grade (depending on whether the student uses or not the score on the subtests), will be mandatory.
Learning outcomes 1.1, 1.2 and 1.3 will be evaluated.
To pass the course a minimum score of 4 (four) out of 10 (ten) on the final comprehensive test, as well as 5 (five) out of 10 (ten) in both the laboratory test (described in paragraph 2 above), and in the final score resulting when including all relevant partial scores.
5.1. Methodological overview
The learning process that is designed for this subject is based on the following:
1. Lectures, given to the entire group, in which the teacher will explain the basic principles of the subject and solve some problems, selected application subject to the degree. These problems are mainly drawn from the collection that the teacher provides the student at the beginning of the semester. The participation of students in this activity by planning sorts of problems will be strengthened. That is, be indicated prior the problems that are to be discussed in the classroom so that the student can reflect on them and intervene in their resolution.
2. Laboratory practices that are distributed throughout the semester and whose assessment will form part of the final grade for the course. Groups of two or three students to work on each laboratory assembly, counting with a script previously delivered by teachers and a questionnaire that collects data and analysis taken form.
3. Small group activities that include seminars that delves into a topic of interest in the subject of the degree, advanced laboratory experiences, supervised student work, etc.
4. Self-employment, studying the matter and apply it to solving exercises. This activity is essential in the process of student learning and overcoming evaluation activities.
5. Tutoring, who can relate to any part of the subject and emphasize that the student go to them with clear and mulled conveniently approaches.
5.2. Learning tasks
The program offered to the student to help him/her achieve the expected results includes the following activities:
Developed throughout the semester by 3 hours of weekly classes on schedule assigned by the center. It is therefore a highly recommended for the proper use of the subject face activity.
2. Laboratory activities:
Will consist of 4 laboratory sessions of two hour each, made in subgroups of the main group of theoretical class. The labs are classroom activities that the student must do to pass the subject; evaluation will be done through a final exam. The time planning will be conducted by the center and communicated at the beginning of the course.
3. Seminar activities
In this classroom activity it will work on problems presented in lectures. There will be 7 sessions of one hour, in which the critical problem solving is encouraged.
4. Study and personal work
This is the part of the course requiring no presence in class. It is estimated as about 85 hours necessary for the study of theory, problem solving and laboratory reviewing scripts.
Professor publish a schedule of attention to students so they can attend to queries in an orderly way throughout the semester.
