Objectives

The course is focused on the study of Mass Transfer phenomena. The students should acquire here sound basic knowledge on:  physical and the mathematical description of  mass transfer mechanisms (diffusion and convection),  transport of a solute between phases in contact,  concept of individual and global mass transfer resistances. They should establish mass balances for different cases/geometries in steady state and transient conditions, definite  appropriate boundary conditions, apply 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, design  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.

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.

Special assessment (TE, DA, ...)
