Learning outcomes

Knowledge and understanding
For a passing grade the student must

• be able to define and/or clarify in short certain basic concepts, principles and phenomena in thermodynamics and fluid mechanics
• be able to shortly account for basic relations considering properties of pure substances, mass and energy conservation, entropy generation and momentum balance, with a basic understanding of limitations and applicability
• be able to derive and account for certain technical important relations within the scope of the subject

Competences and skills
For a passing grade the student must

• be able to demonstrate a good engineering handling practice of property tables and diagrams and to be able to solve basic energy- and fluid-related problems
• be able to describe shortly, clarify and analyse certain thermodynamic processes of technical importance, with a quantitative assessment of its quality regarding the influence on the environment (entropy generation)
• be able to accomplish a complete dimensional analysis of a given dimensional problem
• be able to apply control volume analysis of the balances of mass, energy and linear momentum, for stationary flow with homogeneous in- and outlets
• be able to accomplish a basic fluid mechanical analysis of single pipe systems at stationary incompressible flow conditions, and isentropic compressible flow in nozzles

Judgement and approach
For a passing grade the student must

• be able to produce written communication, on problem-solving and the lab-report, that is well-structured and illustrative, with clear references to external sources, attention to limitations and accuracy, and which demonstrate understanding of the subject

Examination details

Grading scale: TH - (U, 3, 4, 5) - (Fail, Three, Four, Five)
Assessment:

Examination consists of two written tests that include theory and problem solving, assessment of individual written home assignments and laboratory report. The grade is determined by a weighted total score consisting of results from approved exams, and possibly bonus points from approved home assignments, according to a special formula.

The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
