The Computer Controlled Axial Flow Turbine, "TFAC", consists of a small-scale turbine with single-stage axial flow input. It has eight nozzles that act as water rings to the rotor, four of which have an incidence angle of 20º and the other four of 30º. In this way, it is possible to study the differences in the working regime by varying the entry angles into the turbine through eight valves that allow the water to pass to the different nozzles. In order to raise the fluid, it has a computer controlled pump that enables the impelled flow to pass through the turbine, in which part of its energy is left, causing the turbine to turn, overcoming the external resistance caused by an electromagnetic brake. This computer controlled brake makes it possible to vary the braking load on the turbine. In addition, the unit is equipped with a pressure sensor placed at the turbine water inlet which measures the inlet pressure, a flow sensor to measure the turbine water inlet flow, an optical sensor which determines the speed of the turbine shaft and has two pressure sensors at the pump inlet and outlet, in order to obtain its characteristic curve. The pump-turbine group has a tank and a pipes s
