| Teaching Methods | |
|---|---|
| The course consists in front lessons (30h) and classroom exercises (30h) for a total amount of 60 hours which are worth 6 credits. The exercises are conducted in a cooperative way, led by the teacher, with the help of manuals for obtaining data and scientific calculators for numerical analysis. |
| Verification of learning | |
|---|---|
| the assessment of the achievement of the objectives will be done by means of a written test and an oral interview. The written test typically consists of two questions to be answered in three hours. To pass the test, the student must demonstrate to be able to formulate material and energy balances, to properly find the data on the manuals, and to design the calculation procedures for achieving the results. The oral interview typically lasts 30min. The student is required to deal with at least two problems involving thermodynamic aspects and questions are asked to highlight his ability to think on the aspects of interest of the course. The final vote is expressed in a scale from 1 to 30, with a pass grade equal to 18. It is an average of the results achieved in the written and oral tests. It will depend on the degree of maturity acquired on the content and the methodological tools explained in the course, taking into account also the quality of the written and oral exposition and the autonomy of judgment shown. The essential condition to achieve sufficiency is the correct formulation of mass balances with or without chemical reactions, the proper application of the equations for physical equilibria and for chemical equilibrium of gaseous reactions, the capacity to solve simple problems of heat or mass trasfer in steady state conditions. The student reaches the level of excellence once he proves to be able to face problems no not expressly dealt during the lessons. |
