Learning outcome

Knowledge:
The course provides the student with knowledge about:
- Basic design of Centrifugal pumps, Pelton-, Francis-, Kaplan- and gas-turbines.
- Flow conditions and geometrical description of the main components in Centrifugal pumps, Pelton-, Francis-, Kaplan- and gas-turbines.
- Cavitation in Francis turbines
- Surge and chocking in compressors and gas-turbines.
- The course gives the student insight about:
- Basic design of Wind turbines, Reversible Pumpturbines, multi-phase pumps and wet gas compressors.
- Main components in a Hydro Power Plant and Gas Power Plant.

Skills:
The course should enable the student to:
- Calculate the main dimensions of hydro- and gas-turbines.
- Evaluate which turbine to be used in a Hydro Power Plant or a Gas Power Plant.
- Evaluate which pump or compressor to be used in a process-, gas- or a fluid-system.

General competence:
The course should give the student:
- When the student has finished the course, he/she shall have knowledge about Hydro turbines, Gas turbines, Pumpturbines, Centrifugal pumps and Compressors.
- The student will be able to use this knowledge in projects where these turbo machinery is a part of for example a process system or a power plant.
