General proficiencies
Basic or general proficiencies
CB1: Students should demonstrate having and understanding knowledge in a study field starting rom the background of secondary education, and should reach a lever that, although supported by advanced textbooks, also includes some aspects that imply state-of-the-art knowledge in their study field.
CB3: Students should be able to gather and interpret relevant data (usually within their fields of study) to state judgments that include reflection on relevant social, scientific or ethic issues.
CB4: Students should be able to communicate information, ideas, problems and solutions to both a specialist and a non-specialist audience.
Global proficiencies
CG1: Ability to develop and complete industrial engineering projects whose objective is to build, repair, maintain, install and assemble structures, mechanical equipment, energy installations, electric and electronic installations, facilities, and production and assembly processes.
CG2: ability to address the activities under engineering projects described in the previous epigraph.
CG3: knowledge of basic and technological subjects to have the ability to learn new methods and theories, and versatility to adapt to new situations.
CG4: Problem solving proficiency with personal initiative, decision making, creativity and critical reasoning. Ability to elaborate and communicate knowledge, abilities and skills in industrial engineering.
CG5: knowledge to perform measurements, calculations, assessments, appraisals, surveys, studies, reports, work plans and similar work.

Evaluation
| Learning outcome |
Assessment activity |
Weight (%) | It allows test resit |
Minimum required grade |
|---|---|---|---|---|
| R1, R2, R3 y R5 | Written exam, which gathers all the contents of the subject related to heat exchangers. It will consist of a theoretical and a practical part based on exercises and calculations. | 30 % | Yes, at the extraordinary exam | No |
| R6 y R7 | Individual work about thermal modelling of a heat exchanger. Lab session report. | 10 % | Yes, at the extraordinary exam | It is required a 5 out of 10 |
| R1, R2, R3, R4 y R5 | Written exam, which gathers all the contents of the subject. It will consist of a theoretical and a practical part based on exercises and calculations. | 60 % | Yes, at the extraordinary exam | It is required a 3.5 out of 10 at the theory part of the exam |
The final grade of the subject will be obtained with the weighted average of the three tasks. In order to pass the subject it is necessary to obtain 5 (or more) out of 10, besides meeting the minimum criteria requested. The student who does not pass the subject would be able to sit the extraordinary exam; in that case the final grade will be the grade of this exam.
