EMTS2200 Fluid Mechanics Course description

The course will introduce students to fluid mechanics and thereby give them a basic understanding of calculations needed to address flow problems. Theory will be translated into practical application. Students are expected to acquire basic theory on fluid mechanics and an understanding of how to use this theory in practice in technical contexts. The course forms a basis for understanding the operating principles behind various energy systems, the technical units involved and basic dimensioning of such units. Possible practical applications include dimensioning of components in pipe and cable systems (e.g. radiator systems), pressure loss calculations, emptying of vessels, calculation of forces generated by a water flow.

No requirements over and above the admission requirements.

After completing the course, the student is expected to have achieved the following learning outcomes defined in terms of knowledge, skills and general competence:

Knowledge

The student:

• can apply the no-slip condition
• can classify flows and describe laminar and turbulent flows
• can calculate hydrostatic pressure in liquids and corresponding forces on surfaces and buoyancy
• familiar with different methods of pressure measurement
• can visualize a flow field
• can use the continuity equation (conservation of mass)
• is able to use Bernoulli's equation, equation for conservation of mechanical energy
• can calculate forces associated with flow systems
• can analyze flow in pipes, channels, networks. Calculate energy and pressure losses
• can measure flow rates and quantities (mass flow, volume flow)
• can calculate resistance forces (tensile forces) by external flow (flow along surfaces and around bodies)
• can calculate conditions associated with turbomachinery such as pumps and fans

Skills

The student is able to:

• perform necessary calculations for engineering analysis of fluid engineering problems in practical constructions, including piping systems in buildings and in the rest of nature
• calculate pressure drop through a pipe or duct system and then calculate the required pump or fan power
• calculate forces acting between a fluid at rest and a wall, in order to dimension suspension
• calculate forces acting between a fluid flow and the pipe wall, in order to dimension suspension
• calculate how long it takes to empty a tank
• dimension a simple network of pipes/ducts (e.g. radiator system)
• measure flow rates and volume and mass flow
• calculate flow resistance for solid bodies moving relative to a fluid
• choose the right size of pump in a pipe system

General competence

The student is able to:

• contribute to the development of new technology based on an understanding of mathematical modeling and the solution of physical problems
• solve coupled problems related to both fluid mechanics, heat and mass transport and thermodynamics
• assess whether calculation results are reasonable and the validity of the mathematical model

The course will give students the knowledge required to understand and produce various types of building technology drawings, knowledge of building technology principles, choice of materials and detailed solutions, with the main emphasis on wooden houses and why these solutions were chosen. The course shall also teach students about the use of computer technology and further develop their skills in producing drawings using 3D modelling software.

No requirements over and above the admission requirements.

After completing the course, the student is expected to have achieved the following learning outcomes defined in terms of knowledge, skills and general competence:

Knowledge

The student:

• knows the principles for producing drawings manually and using modern BIM tools
• is familiar with relevant design solutions and materials with the main emphasis on small wooden houses
• is familiar with how Norwegian standards NS 3420 and NS 3451 are structured

Skills

The student:

• is capable of manually drawing common graphical projections of simple objects
• is capable of producing various building technology drawings, both manually and using 3D modelling software
• is capable of choosing materials, solutions and components for small wooden houses and of explaining the reasons for his/her choices
• is capable of preparing an itemised description in accordance with Norwegian standard NS3420 and of calculating building costs using BIM technology

General competence

The student:

• is able to choose, justify, present and discuss his/her professional choice of building materials and solutions for small wooden houses

Lectures and project work. The project work takes place in groups, where the students will continue to work on the BIM model produced during the course BYFE1201 Introduction to Building Professions.

The following coursework is compulsory and must be approved before the student can sit the exam:

• 2 assignments in connection with training in Revit, 8 hours
• 3 individual assignments, manual drawing of building details, 9 hours
• Project work in groups, with submission of 4 sub-assignments, 20 hours

Individual written exam, 3 hours

The result of the exam can be appealed.
