Methodologies |
Description | |
Practicals using information and communication technologies (ICTs) in computer rooms | We will work through internet in a project with another professor from a foreign country. Using platforms through internet, mobile phone... We will received a visit from University of Bordeaux who will teach one week to learnt about project base learning project. Some test will be done after the depart of the teacher from University of Bordeaux. |
Laboratory practicals | Complete the tasks asked during the practises, attending the laboratory practises. |
Problem solving, classroom exercises | Problems solved in class, and others done by the students at home. They may be explained in detail during tutorial also. |
Lecture | Classes teaching the theoretical concepts of fluid dynamics and statics and functioning of pumps and turbines, and also de types. |
