Air Operated Reaction Turbine

This demonstration unit is part of an equipment series that facilitated investigations on pneumatically driven turbines. The flow rate in the system is measured with a variable-area flowmeter. For the operation of the unit, a mains connection and a compressed air supply are required. Inlet and outlet pressure at the turbine are indicated on easy to read dial instruments. For exact measurements the table unit is equipped with electronic sensors for recording temperature, speed and torque, the values recorded are indicated on digital displays.
