Fluid Mechanics
Presentation
The scope of Fluid Mechanics is wide (Earth's surface enveloped by air and water) finding applications in traditional areas of engineering (mechanical, chemical, civl) and others such as energy and environment, aerospace, bioengineering. Practical applications involving the analysis and design of systems that require a good understanding of fluid mechanics: aerodynamics (aeronautics and aerospace, automotive), distribution networks (water, oil, natural gas), air conditioning and ventilation, biomedical engineering ( breathing and blood circulation), biomechanics, sports, etc. The relevance of Fluid Mechanics in Aerospace Engineering is manifested in several domains, for example: atmospheric behavior, aircraft and rocket aerodynamics (drag and lift forces, flight mechanics and stability), aircraft propulsion, energy consumption, and pressure and velocity measurement.

 Calculate pressure drop and size fluid transport facilities
 Determine drag and lift forces
Teaching methodologies and assessment
METHODOLOGY OF TEACHING: The class structure is divided into theoretical and practical sessions. The theoretical sessions are given remotely through the TEAMS platform, using audiovisual media for the presentation of the subjects. In the practical sessions, students are confronted with problems / situations, to be carried out individually or in groups, with the help of the teacher, where they can apply the acquired knowledge. These sessions are expected to contribute to a good teacherstudent relationship and greater proximity between them.
EVALUATION: Continuous incidence according to the ULP Knowledge Assessment Regulations.
Two tests will be carried out: the first approximately two thirds of the semester and the second shortly after the end of classes
Final Note: NF = 0.80xNT + 0.15xNP + 0.05xNE
NT: Arithmetic mean of test scores
NP: Performance in solving proposed problems
NE: Class dedication and participation
