Aim
The aim of the course is to acquaint students with the principles of calculating transient states in flow engineering piping systems. Its topics include drinking water supply systems, sewerage and sewage networks, as well as pneumatic piping systems and equipment. Basic knowledge of fluid science, thermology, and engineering mathematics are essential for this. Within the framework of the course, in addition to theoretical lectures, students solve a half-year project task in groups of 2-3 people and report on their knowledge in a summary performance evaluation. At the end of the semester, the project task is documented in writing and presented in a presentation.

During broadening his/her knowledge the student cooperates with the teaching staff. Readily accepts reasonable professional and other criticism. In certain situations, as a member of a team, the student cooperates with his/her fellow students in solving a task. In possession of his/her knowledge, on the basis of analysis, the student makes a well-founded, responsible decision. The student thinks over the tasks and the problems and solves them independently based on the given sources. The student is committed to the methods and principles of systemic thinking and problem-solving.
Teaching methodology
During the teaching of the subject, the lectures and exercises are closely related in terms of content. The lectures basically introduce students to the information defined by the knowledge competence elements using the technique of frontal education. Some of the lectures come with pre-published slide shows so students can add their own notes to the lecture. Based on the material of the lectures, the appropriate preparation for the summary evaluations can be achieved. During the practical sessions, the competence elements can be deepened by performing and evaluating project tasks closely related to the topic of the subject. To develop teamwork skills, students work in groups during the lab and then submit documentation on the work done in groups.

General rules
Learning outcomes are determined on the basis of performance evaluation: test and project task documentation. Performance appraisal is used for the complex, written control of the subject elements of the subject's knowledge, ability and independence and responsibility. On the one hand, the documentation focuses on the application of the acquired knowledge, so it focuses on problem recognition and solution, and on the other hand, it asks for the necessary lexical knowledge during the performance evaluation, the available working time is 90 minutes. Partial performance assessment is a complex way of assessing the competency elements of the subject's ability, attitude, and independence and responsibility type, the form of which is the group-prepared documentation of the project carried out during the semester.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | summative assessment | |
| Number: | 1 | |
| Purpose, description: | Summative assessment measures students ’learning outcomes determined by knowledge and ability type competencies. Accordingly, the test assesses the existence of the designated theoretical knowledge and the application of skills. It will be completed on the date specified in the study performance assessment plan, expected to be in the 14th week of education. 50 points can be obtained in the summary test. | |
| Mid-term assessment No. 2 | ||
| Type: | formative assessment, point-in-time personal act | |
| Number: | 1 | |
| Purpose, description: | The mid-year performance is evaluated on the basis of the documentation submitted by the project team based on the application of the acquired theoretical knowledge to a practical problem. A maximum of 50 points is available for project work based on the thoroughness, practicality of the solution method and the quality of the documentation. It is not possible to differentiate between students in the project group according to their contribution to success. | |
Detailed description of assessments performed during the examination period
The subject does not include assessment during the examination period.
The weight of mid-term assessments in signing or in final grading
| ID | Proportion |
|---|---|
| Mid-term assessment No. 1 | 50 % |
| Mid-term assessment No. 2 | 50 % |
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
There is no exam belongs to the subject.
Determination of the grade
| Grade | ECTS | The grade expressed in percents |
|---|---|---|
| very good (5) | Excellent [A] | above 95 % |
| very good (5) | Very Good [B] | 88 % - 95 % |
| good (4) | Good [C] | 75 % - 88 % |
| satisfactory (3) | Satisfactory [D] | 63 % - 75 % |
| sufficient (2) | Pass [E] | 50 % - 63 % |
| insufficient (1) | Fail [F] | below 50 % |
