Fluid Thermodynamics
Objectives
After this curricular unit, a student will be able to:
-Understand and know how to apply the principles of conservation of the mass and energy, in the integral formulation, for an open system (control volume). Psychrometric analysis.
-Understand the main concepts of the Fluid Mechanics.
-Know the techniques and equipment for the measurement of pressure, velocity, temperature and flow.
-Calculate pressures and velocities in flows using Bernoulli equation. Design the installation characteristic curve and choose a pump.
-Apply similarity concepts and dimensional analysis.
-Know the fundamental modes of heat transfer and solve basic problems of conduction, natural and forced convection using empirical correlations.

Teaching method
The lectures will be as interactive with the students as possible. The students are encouraged to raise questions about the topics being discussed in a lecture.
In the problem-solving sessions, problems are proposed to the students with the goals: to exercise their critical thinking and ability to discuss ideas, to consolidate their use of terminology, as well as to prepare for an exam.
