Unit: HTRC. Experimental Reaction Turbine

1.- Visual examination of a small reaction turbine.

2.- Production of torque/speed and power/speed curves.

3.- Evaluation of specific air consumption at a range of speeds and pressures.

4.- Application of the First Law to a simple open system undergoing a steady flow pressure.

5.- Determination of the isentropic efficiency of a reaction turbine and plotting the end states on a temperature/entropy diagram.

6.- Construction of retardation curve and the determination of resisting torques due to bearing friction, disc friction and windage, at different speeds.

7.- Obtaining the inlet pressure effect on the outlet power and effectiveness of the turbine, as well as torque, speed and power curves.

Other possible practices:

8.- Sensors calibration.

9-27.- Practices with PLC.
