Course detail

Hydraulic Processes

FSI-DHPAcad. year: 2014/2015

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 and disposal of pollutants as the by-products of waste energy utilization technology.
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 from this course can be applied in many industrial areas.

Learning outcomes of the course unit

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 equipments including pipies, filters, pumps, compressors etc.

Prerequisites

Basic knowledge of mathematics and physics.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.

Assesment methods and criteria linked to learning outcomes

EXERCISE:
Regular and active attendance is required. Next two tests have to be passed successfully. Each test consists of two theoretical questions and two exercises. Maximum number of points from each test is 10. The criterion of passing each test is to obtain more than half number of points. The student has the possibility of one repeat. The obtained points from tests are carried to the exam.
EXAM:
The exam consists of written and oral part. The written test comprises one exercise and preparation of answers for the theoretical questions that will be discussed within the oral part of the exam. The maximum number of points from the exam is 50.
Thus the overall number of points that can be obtained within the subject is 70.
EVALUATION:
64 - 70 A
58 – 63 B
51 – 57 C
44 – 50 D
36 - 43 E

Aims

The aim of the course is to make students familiar with the theoretical knowledlge of unit operations and apparatus used in chemical, foodstuffs and biotechnological industry. Another aim of the course is to get 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.
