Learning objectives

<br />The course provides the students with the necessary knowledge related with fluid mechanics in the context of classical mechanics. The students will be able to solve the main technical problems related with the interaction between fluids and structures and with pressurized flow. Numerical exercises about the topics listed in the program will be developed.

Prerequisites

<br />Differential analysis AB and C, Geometry, General Physics AB.
