Hydropower Laboratory
The total area is 400 m2, where approximately 100 m2 are workshop facilities.
The laboratory, which is very suitable for building small test rigs, is equipped with three circulation systems:

Francis turbine
The rig, which is designed for tests by advanced students, allows opportunities for measuring relative efficiencies.
- Maximum head: 12 mWc.
- Maximum flow: 0,4 m3/s.
The generator has a maximum speed of 2700 rpm giving a power output of 132 kW. The turbine’s outlet diameter is more than 300 mm.
Pelton turbine
The test rig for Pelton turbines has one jet and the possibility to visualize flow in the buckets. It is also possible to measure relative efficiencies.
The following limitations apply to the test rig:
- Maximum and minimum diameter: Respectively 500 and 300 mm.
- Nozzle diameter: 40 mm. The needle is variable and electronically controlled.
- Maximum head: 90 mWc. Maximum flow: 0,09 m3/s.
- The generator has a maximum speed of 1500 rpm giving a power output of 80 kW
Cavitation rig
- The rig is utilized to characterize the cavitation properties of materials.
- Maximum power: 18 kW.
Peripheral speed when cavitation occurs: 40 m/s.
- All materials, normally exposed to cavitation erosion, may be tested and characterized
