Real time curves representation about system responses. Storage of all the process data and results in a file. Graphic representation, in real time, of all the process/system responses. All the actuators’ values can be changed at any time from the keyboard allowing the analysis about curves and responses of the whole process. All the actuators and sensors values and their responses are placed in only one computer screen
Capabilities:
Determining the operating characteristics, i.e. power, efficiency and torque, of a Francis Turbine at various speeds and guide vane openings
A tapering, spiral shaped volute conveys water to the runner via a ring of guide vanes that are adjustable in angle to vary the flow through the turbine
Power generated by turbine is absorbed by a Prony friction brake consisting of a pair of spring balances attached to a brake belt that is wrapped around a pulley wheel driven by the runner. The load on the turbine can be varied by tensioning both spring balances which increases the friction on the pulley wheel The head of water entering the turbine should be able to be indicated on a Bourdon gauge and the speed of rotation to be measured using a noncontacting tachometer
Tachometer to be supplied  
The volute of the Francis turbine should incorporate a transparent front cover for clear visualisation of the runner and guide vanes
