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
• classify flows and describe laminar and turbulent flows
• calculate hydrostatic pressure in liquids and corresponding forces on surfaces and buoyancy
• explain different methods of pressure measurement
• visualize a flow field
• use the continuity equation (conservation of mass)
• use Bernoulli's equation, equation for conservation of mechanical energy
• calculate forces associated with flow systems
• analyze flow in pipes, channels, networks. Calculate energy and pressure losses
• measure flow rates and quantities (mass flow, volume flow)
• calculate resistance forces (tensile forces) by external flow (flow along surfaces and around bodies)
• calculate conditions associated with turbomachinery such as pumps and fans

Skills

The student can:

• 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 can:

• 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
