Features:

• Water turbines are turbo machines utilizing waterpower. 
• The Pelton turbine is a type of impulse turbine; such turbines convert the pressure energy of water into kinetic energy entirely in the distributor. 
• During the conversion, the water jet is accelerated in a nozzle and directed onto the blades of the Pelton wheel tangentially. 
• The water jet is redirected by approximately 180° in the blades. 
• The impulse of the water jet is transmitted to the Pelton wheel.
• The turbine torque is determined by force measurement on a band brake and is read on spring balances. 
• For measuring the rotational speed, a non-contact speed sensor, is required. 
• A manometer shows the water pressure at the turbine inlet.
