AFF073 Experiments with an Action Turbine Didactic Equipment Teaching Equipment Hydrodynamics Lab Equipment
Learning Objectives / Experiments
- principle of operation of an action turbine
- characteristic curves at constant height of fall
* relationship between torque and speed
* efficiency dependent on speed
* flow rate dependent on speed
* hydraulic power and mechanical power dependent on speed
- evaluation of measuring values and characteristics based on the theory
- partial load behaviour with controlling the number of nozzles in comparison to throttle control
