Objectives

The main objective of this course is to provide students with the basic physical knowledge and mathematical tools necessary to study the motion of a fluid and the design of simple fluid systems commonly found in process indiustry.

Acquired skills

- Physical interpretation of basic fluid mechanics phenomena.
- Mathematical modelling of basic fluid mechanics phenomena.
