# 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.
