Course detail

Experimental Methods

FSI-KEMAcad. year: 2017/2018

The knowledge of physical properties of substances that are not so usual is important for the design of process equipment. These properties cannot be always defined by calculation; therefore they have to be determined experimentally. The result of such experiments is e.g. an invariable required for the design of process equipment based on modelling. To understand better the individual unit operations of the process engineering it is useful to demonstrate these operations in laboratory conditions.

Learning outcomes of the course unit

The course is a follow-up to other theoretical courses. Besides the description of individual experimental methods it is concerned with the organisation and work safety at laboratories, processing and interpretation of measured readings with their possible graphic expression in reports. Assignments are selected with regard to the practical needs of a process engineer.

Prerequisites

Knowledge of physics, mechanics, and chemistry at the level of the lectures presented at the study of the Faculty of Mechanical Engineering is assumed.

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. The attendance at lectures is recommended. Teaching is suplemented by practical laboratory work.

Assesment methods and criteria linked to learning outcomes

Course-unit credit requirements: Attendance at seminars. Submitting reports on experimental measuring.Examination is oral. Students demonstrate the level of the acquired knowledge.

Aims

The course objective is to make students familiar with laboratory work, selected experimental methods, evaluating and processing experimental results. A part of the lessons is held in the laboratory, where various assignments are solved. Experimental methods complete the theoretical part of the study. At lectures students are made familiar with the possibility to measure basic physical variables, which are important for the process engineering and with principles of instruments used in the technical practice. They will realize the importance of experimental methods as the only way of verifiyng the theoretical findings and the importance of the experiment as the basic step for developing the theory of unit operations in the process engineering.

Specification of controlled education, way of implementation and compensation for absences

The attendance at lectures is recommended. The attendance at exercises is compulsory and checked.
At seminars reports on experimental measuring are worked out. The attendance is required. Absences must be compensated
