Turbo-machinery and hydro power plants: wind turbines, types of hydraulic turbines, main components, small hydro power plants and pumps, turbine scaling laws. Cavitation. Examples of fluid mechanics problems related to renewable energy.

### Learning outcome

Provide the basic elements of the theoretical foundations for fluid flows. Through problem sessions provide sufficient training to enable the students to formulate and solve practical flow problems. Knowledge, after completion of this course, the student will have knowledge on: - solving hydrostatic problems:  describe the physical properties of a fluid.  calculate the pressure distribution for incompressible fluids.  calculate the hydrostatic pressure and force on plane surfaces.  demonstrate the application point of hydrostatic forces on plane surfaces.  formulate the problems on buoyancy and solve them. - describing the principles of motion of fluids in relation to: - Velocity field, substantial derivative, streamlines and pathlines. - Navier-Stokes equations for viscous flow.  internal flow  external flow - pressure losses in pipe systems - calculating forces on objects immersed in fluid flow - dimensionless numbers and their use in fluid mechanics problem - identifying derivation of basic equations of fluid mechanics, with related assumptions, and applying:  Bernoulli equation  the equation of the conservation of mass.  the equation of linear and angular momentum  the equation of the conservation of energy. - main components of hydro power plants and hydro turbines - calculating power extraction and production in hydropower plants and pump systems Skills, after completion of this course, the student will have skills on: - Evaluation of models for flow analysis. - Use of control volume analysis. - Computation of forces and moments from fluid on solid bodies. - Derivation and use of formulae and tables for flows. - Solution of the basic laws of fluid mechanics for simple flow problems. General competence, after completion of this course, the student will have general competence on: - The basic elements of the theoretical foundations for fluid flows. - Formulation and solution of practical flow problems.

### Learning methods and activities

Lectures, example exercises, practice exercises and self-study. A specified number of the exercises as well as a laboratory exercises must be approved before final exam.

• Exercises
• Lab. work

### Further on evaluation

The subject is taught as as video-lecture from Trondheim to Gjøvik and Ålesund. The exam text will be the same for FENT2002 Fluid Mechanics and hydraulics, FENA2002 and FENG2002. The re-sit examination might be changed from written to oral.
