Objectives

The course is focused on the study of Mass Transfer phenomena. The students should acquire here sound basic knowledge on: the physical and the mathematical description of the mass transfer mechanisms (diffusion and convection), the transport of a solute between phases in contact, the concept of individual and global mass transfer resistances, establishing mass balances for different cases/geometries in steady state and transient conditions, definition of appropriate boundary conditions, application of the acquired concepts to the design of some mass transfer equipment and developing the skill of problem solving.

Learning outcomes and competences

Learning Outcomes - solve problems involving mass transport, designe  of simple  mass transfer equipment

Skillsa cquisition - application of critical thinking to solve engineering problems involving mass transport, development of capabilitiesi of knowledge ntegration ,  teamwork stimulation.

Teaching methods and learning activities

The theoretical concepts and mathematical description are given in the theoretical/practical contact hours of each week to the whole course during the whole semester and complemented by the resolution of illustrative problems. Some small debates/discussions about raised questions will occur to stimulate students´ critical thinking In these classes especial attention is devoted to the improvement of students' problem solving ability. When possible, this strategy will involve some operating steps: problem definition, exploration, planning of the resolution, resolution, critical analysis of results and generalization.

Evaluation Type

Distributed evaluation with final exam

Assessment Components

Designation	Weight (%)
Exame	70,00
Trabalho escrito	30,00
Total:	100,00

Eligibility for exams

Students have to do the following assignment to be admitted to exams: solve two problems (one individually, another in group) and  do a short examination.
Students, who attended to this course in the previous years, can either do the assignment/problem solving, or just the final exam.

Calculation formula of final grade

Final Mark: FM
FM= 0,30 x CA + 0,70 x FE

CA- Continuous Assessment- one rindividual problem, one problem solved in group and a short examination.
FE- Final exam

Students have to reach a minimum grade of 8 out 20 in the final exam.

Examinations or Special Assignments

Solve one rindividual problem 2 points, one problem solved in group 1 point and a short examination 3 points (total of 6 points)

Special assessment (TE, DA, ...)
