Prerequisites
Basic knowledges of mathematical analysis and physics

Learning outcomes
KNOWLEDGE AND UNDERSTANDING:
To provide a comprehensive treatment of engineering thermodynamics from the classical viewpoint and the basis in fluid mechanics and heat transfer with applications in the field of biomedical engineering.
CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
This course is part of the base engineering courses, related to Industrial Engineering, and will provide knowledge about the principles that form the basis of thermodynamic processes, the mechanisms of heat transfer and fluid dynamics.This knowledge is acquired through lectures and exercises.
TRANSVERSAL SKILLS:
The theory and exercises of the course will help to improve the degree of autonomy, the ability to learn and to draw conclusions.
