Learning outcomes Students should acquire the basic knowledge about mass transfer, heat transfer and momentum in order to understand the importance of these phenomena in reactional processes and in unit operations.
At the end of the Curricular Unit, the student should be able to: describe the mechanisms of mass and heat transfer and momentum; apply Bernoulli's equation; identify the transport phenomena involved in the different unit operations and chemical and/or biochemical transformation processes; apply the concepts acquired in understanding experimental work and solving problems; understand the importance of these phenomena in the global speed of chemical processes.

Teaching Methodologies and Assessment Criteria In order to obtain the desired skills and learning outcomes, theoretical classes, theoretical-practical classes (TP) and practical classes are taught. In theoretical classes, the concepts and fundamentals of transfer phenomena are exposed, their mathematical translation and application to unit operations and reaction steps. In TP classes, students solve different problems, which require the application of knowledge, consolidating the conceptual aspects. In practical classes, experimental activities are carried out in groups involving the determination of diffusion coefficients in a continuous medium, individual and global heat transfer coefficients and global volumetric mass transfer coefficients.

The evaluation includes:
2 tests (contents of theoretical and theoretical-practical classes): 80%
Laboratorial activities (reports and oral presentation of one of them): 10%
Summarized reports of the remaining laboratory work: 10%
Language Portuguese. Tutorial support is available in English.
