Course detail

Hydraulic Processes

FSI-KHLAcad. year: 2023/2024

The course is focused on unit operations in the liquid medium, i.e., gaseous and/or liquid. The aim of the course is to introduce the theoretical basics of unit operations of process engineering that are characterized by mass and momentum transfer in liquid medium with different rheological properties. Many of the unit operations are parts of technologies focused on the waste energy utilization, disposal of pollutants as the by-products of waste energy utilization technology, and waste-water treatment.
Besides the theoretical knowledge the emphasis is put on the constructional and ecological design of individual apparatus, and on the design of their main dimensions. The attention is aimed to unit operations like the transportation of liquids and gases, flow through porous material, filtration, gravitational and centrifugal sedimentation, mixing, fluidization, and operations related to waste-water treatment technology. The knowledge gained in this course can be applied in many industrial areas.

Rules for evaluation and completion of the course

SEMINARS: Regular and active attendance is required and checked. Two tests must be passed successfully. Each test consists of three examples (each for 5 points). Thus the maximum number of points gained from each test is 15. Each test is successfully passed if more than 7 points are obtained. The student has the possibility of one repeat. The obtained points from tests are carried to the exam.

EXAM: The exam is only written. It consists of 10 questions related to the theory of presented at lectures (1 question = 4 points). The maximum number of points from the exam is 40, and the overall number of points that can be obtained within the course is 70. The course evaluation is then as follows:

64 – 70 A

58 – 63 B

51 – 57 C

44 – 50 D

36 – 43 E

0 – 35 F


The attendance at seminars is checked. Two non-excused absences are allowed. The lectures are optional.

Aims

The aim of the course is to make students familiar with the theoretical knowledge of unit operations and apparatus used in chemical, foodstuffs and process industry, and biotechnological industry. Another aim of the course is to gain the knowledge about the constructional principles and use of pumps and compressors in those technologies. The acquired knowledge can be also used in other industrial branches.
The course enables students to apply the theoretical knowledge on the particular process equipment and apparatus. The students should be able to design the main dimensions of process plant equipment including pipes, filters, pumps, compressors etc.
