Objectives
-
Learn the main concepts of the Fluid Mechanics.
-
Learn and know how to apply the principles of conservation of the mass, momentum, angular momentum and energy in the integral and in the differential formulation.
-
Learn to solve concrete problems of Fluid Mechanics in any area of engineering, particularly in the area of Mechanical engineering.

Laboratory sessions.
Evaluation method
1.The evaluation consists of 3 mini-tests lasting 1 hour each.
2.The final grade is obtained by the simple arithmetic average of the test grades.
3. If the final grade obtained by the student is over 16, the student may opt to stay with a final grade of 16 or perform an complementary oral exame.
4. In the evaluation tests (mini-tests or exam) is mandatory that students are accompanied his citizen card. Students should carry only a calculator, white sheets and blue / black pen. The calculator can only be a basic scientific calculator. Are not allowed calculators with alphanumeric memory. It is expressly forbidden the use mobile phones during the tests/exam. Failure to comply with this section is assumed to be fraudulent act.
