Objetivos
This unit curriculum is intended that students achieve the following objectives: physical and mathematical understanding of the mechanisms of mass transfer (diffusion and convection), acquisition of solid knowledge about transport of a component between phases in contact, understanding of the concept of transfer resistance mass and global resistance, to be able to establish macroscopic and microscopic balances of mass, in different geometries, both in steady state, both in the transient regime, ability to apply concepts acquired in some simple equipment, developing the skill to solve technology problems.

1 - Diffusion. Definitions of velocities and mass fluxes. Diffusion: 1st Fick's law. Diffusion through a stagnant film. Transient diffusion: 2nd Fick's Law. Diffusion and convection. 2. Convection. The equations of continuity for binary systems. Mass transfer coefficients at low mass transfer rates in one phase. Dimensionless numbers and empirical correlations. Mass transfer in two-phase systems. Overall mass transfer coefficients.

Métodos de ensino e atividades de aprendizagem
Exposition of the concepts in a theoretical class with illustration of some typical exercises and resolution of activities by the students. Resolution of exercises in theoretical-practical classes.
Total online evaluation:
Continuous assessment - 6 class exercises (15% each) and 10% moodle activities
or
100% Exam
face-to-face evaluation:
2 tests (45% each) and 10% moodle activities
or
100% Exam
If the assessment starts on-line and goes face-to-face:
Continuous assessment - 3 class exercises (15% each) and 1 test (45%) 10% moodle activities
or
100% Exam
In exams on-line there are oral evidence of positive evaluations.
In online assessments, students must have their camera turned on and must present an identification element.
If any indication of fraud is detected, the assessment test will be canceled.
