Learning Objectives / Experiments

principle of operation of a reaction 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 depending on speed

evaluation of measuring values and characteristics based on the theory

Specification

[1] turbine to place upon the base unit  

[2] functioning and operating behaviour of a reaction turbine

[3] transparent housing for observing the discharged water jet

[4] constant pressure of the turbine represents in practice the height difference and is adjusted via

Base unit for turbines
