Base Knowledge
Good background in Physics and Mathematics
Teaching Methodologies
Theoretical classes exposing the contents of the curricular unit using wherever possible the presentation of examples within a Bioengineering context in all its branches and theoretical practices classes for solving problems of application. In theoretical practices classes, after a general discussion about the problems, students are encouraged to continue with its resolutions and at the end a discussion of the results is made. The problems proposed to solve in the theoretical practices classes are available to the students in advance.
Learning Results
The purpose of this course is to provide students with the fundamental knowledge of fluid mechanics and apply them to natural or engineered biological systems. The objectives to be achieved by students attending this course are: i) Understand the basic principles of fluid mechanics like viscosity, pressure, continuity equation, principle of conservation of energy, viscous dissipation and boundary layer; ii) Ability to apply fundamental principles to derive governing equations in fluid flow, namely Bernoulli equation; ii) Understand the flow of fluids through pipes and distinction between laminar and turbulent regimes; iv) Calculation of head losses in pipes and accidents for incompressible fluids; v) Selection of pumps.
