Course detail

Hydraulic Processes

FSI-DHPAcad. year: 2018/2019

The course provides students with basic theories of mechanics of liquids and gases (fluids) so that they are able to apply them to simple systems, to explain and predict their behavior. Acquired knowledge is a prerequisite for understanding the theoretical foundations of modern technical disciplines. Findings from this course can be applied in many industrial fields.

Learning outcomes of the course unit

The course enables students to acquire knowledge about the liquid properties, the balance of forces in motionless fluids, motion of the fluid in the force fields, the foundations of hydraulic machines. Students learn to work with the pump characteristics, design and dimension simple piping systems and create models for the study of selected technical problems. It has proved to propose design and main dimensions for the optimal solution for a given technological problem.

Prerequisites

General knowledge of mathematics and physics in courses on FME. Basic knowledge of differential and integral calculus.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Lecture: 13 x 2 hrs. Excercise: 9 x 2 hrs. Exercise with computer labs: 4 x 2 hrs.

Assesment methods and criteria linked to learning outcomes

Credit conditions: attendance at seminars. Obtaining a classification grade E to control work in theoretical exercises, whose term action is set at the beginning of the semester. If this condition is not satisfied, the teacher may in justified cases set a condition. Completing all tasks in the laboratory exercises, fulfilling the conditions for ongoing review and submission of required written. The exam checks knowledge of the laws and their application in practice. The exam consists of three parts. Part 1: test - the student has to show basic theoretical knowledge from hydromechanics Part 2: examples - in this section, students will demonstrate the ability to solve specific examples Part 3: oral exam - this part is used for the classification.

Aims

The aim of the course is to familiarise students with the basic theories of classical and modern hydromechanics so that they are able to apply them to simple systems, to explain and predict their behavior. The challenge is to make students aware that fluid mechanics is the theoretical basis and the result of engineering disciplines. Furthermore familiar with basic design principles and piping systems using pumps and prove to choose the best type of equipment and determine its main dimensions and parameters.
