Teaching method

Lectures combine the presentation of the theoretical concepts with the use of slide projection containing schematic illustrations with important aspects related to the subject and the resolution of exercises by the students. Group resolution is encouraged. At the end of each class the problem is solved.

Evaluation method

The continuous assessment of the subject is composed of two components:

1.Accomplishment of 4 mini-tests throughout the semester, with the average of the marks contributing to 10% of the final mark. These tests are performed on Moodle platform with multiple choice questions with quick answer and/or involving few calculations.

2. Two tests: the first has a 50% contribution and the second a 40% contribution to the final mark. The assessment is individual. Each test is assessed from 0 to 20 points. The minimum mark in the 1st test is 9.5

Each test includes questions on theoretical subjects, worth 6 marks, and problem-solving questions, worth 14 marks.

The subjects covered in each test will be as follows: 1st Test - Momentum transport; 2nd Test - Heat transport.

Final mark = 0.50 × 1st Test mark + 0.40 × 2nd Test mark + 0.10 × average marks of the 4 quizzes

The final mark, rounded up to the nearest whole number, must be greater than or equal to 10 for approval in the subject.

If a student fails the 1st component of continuous assessment or chooses not to take the continuous assessment they will be entitled to sit an exam. A minimum classification of 10 (9.5) on a scale of 0 to 20 is required.
