Aim
The aim of the course is to introduce the basic physical and mechanical quantities, the required concepts and methods to study machines and processes. The aim is also to describe the steady-state operation of the machines, the work, the efficiency, the various drives (friction, belt, gear, worm), the load factor, and the losses. In addition, the course aims to introduce the basics of flow processes, the Bernoulli equation, the Venturi tube, the basics of caloric processes, the concepts of heating value, specific consumption and the enthalpy, the cycle of a thermal power plant, the variable speed operation of machines, the basics of coulisse and crank mechanism, piston pumps and internal combustion engines, the indicator diagram, and the terms of the characteristic curve and the operating point.

Using his/her knowledge, the student makes a responsible, well-founded decision based on his/her analysis.
Teaching methodology
The mid-term evaluation of the formulated learning outcomes is performed as follows: the students must complete six laboratory measurements, the conditions of which are to answer the entry questions and to present the protocol prepared during the measurements. In addition, the condition for obtaining the signature is the completion of at least a sufficient level of 1 summary performance evaluation (written test). The subject ends with an exam.

General rules
The mid-semester evaluation of the formulated learning outcomes is carried out as follows: students must complete six laboratory measurements, the conditions of which are to answer the questions that pop up and present the report made during the measurements. In addition, the condition for obtaining the signature is the completion of at least a sufficient level of 1 summative performance evaluation (Zartel thesis). The subject ends with an exam.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | diagnostic assessment | |
| Number: | 6 | |
| Purpose, description: | A simplified way of assessing the knowledge, ability, attitude, as well as autonomy and responsibility type competence elements of the subject, the form of which is a prepared appearance and active participation in laboratory exercises, which results in a measurement protocol prepared at a sufficient level on site; the uniform assessment principles are defined jointly by the person in charge of the subject and the lecturer of the subject; rating may be ‘pass’ or ‘failed’. | |
| Mid-term assessment No. 2 | ||
| Type: | summative assessment | |
| Number: | 1 | |
| Purpose, description: | The complex, written way of evaluating the knowledge and ability type competence elements of the subject in the form of a written test, the test basically focuses on the application of the acquired knowledge, so it focuses on problem recognition and solution and requires the recognition and interpretation of certain concepts and the relationships between them. The part of the curriculum on which the assessment is based is determined by the lecturer of the subject in agreement with the tutors. The available working time (approximately 75 minutes) is determined by the lecturer, and the evaluation is based on the score obtained. | |
Detailed description of assessments performed during the examination period
Elements of the exam:
| Written partial exam | ||
| Obligation: | mandatory (partial) exam unit, failing the unit results in fail (1) exam result | |
| Description: | A complex, written way of evaluating the knowledge and ability-type competence elements of the subject in the form of an exam, which may consist of calculational tasks that focus on the problem-recognizing-solving ability, as it basically focuses on the application of the acquired knowledge; it may also consist of short theoretical questions assessing lexical knowledge; and essay questions that examine the ability to synthesize. The part of the curriculum on which the assessment is based is determined by the lecturer of the subject in agreement with the supervisors, the available working time is approx. 90 min. | |
The weight of mid-term assessments in signing or in final grading
| ID | Proportion |
|---|---|
| Mid-term assessment No. 1 | 15 % |
| Mid-term assessment No. 2 | 85 % |
The condition for signing is that the score obtained in the mid-year assessments is at least 50%.
The weight of partial exams in grade
| Type: | Proportion |
|---|---|
| Written partial exam | 100 % |
Determination of the grade
| Grade | ECTS | The grade expressed in percents |
|---|---|---|
| very good (5) | Excellent [A] | above 90 % |
| very good (5) | Very Good [B] | 85 % - 90 % |
| good (4) | Good [C] | 73 % - 85 % |
| satisfactory (3) | Satisfactory [D] | 65 % - 73 % |
| sufficient (2) | Pass [E] | 50 % - 65 % |
| insufficient (1) | Fail [F] | below 50 % |
The lower limit specified for each grade already belongs to that grade.
Attendance and participation requirements
The lack of the value means that there is no attendance requirement.
At least 70% the exercises (rounded down) must be actively attended.
At least 85% of laboratory practices (rounded down) must be actively attended.
Special rules for improving, retaken and replacement
The special rules for improving, retaken and replacement shall be interpreted and applied in conjunction with the general rules of the CoS (TVSZ).
| Need mid-term assessment to invidually complete? | ||
| yes | ||
| The way of retaking or improving a summary assessment for the first time: | ||
| each summative assessment can be retaken or improved | ||
| Is the retaking-improving of a summary assessment allowed, and if so, than which form: | ||
| retake or grade-improving exam not possible | ||
| Taking into account the previous result in case of improvement, retaken-improvement: | ||
| new result overrides previous result | ||
| Completion of unfinished laboratory exercises: | ||
| missed laboratory practices must be performed in the repeat period | ||
| Repetition of laboratory exercises that performed incorrectly (eg.: mistake in documentation) | ||
| incorrectly performed laboratory practice (e.g. Incomplete/incorrect report) can be corrected upon improved re-submission | ||
