Procedure
Turbine Generator
 

At your lab station, you should find an experimental set-up as shown in the diagram to the right.  You should also find an 800 mL beaker and a 100 ml graduated cylinder for putting water into the upper container.  If you do not find these things at your station, please see your lab instructor for help.  Place the turbine generator in the tray to catch the water that leaves the turbine.  Note: This tray must be emptied after 2-3 runs to ensure that the hole in the bottom of the generator is not plugged by water.  Connect the voltage sensor to both sides of the output from the generator.  Make sure that the Data Studio software is running on the computer.  If it is not, or if you need help running it, see your lab instructor.  Place the water container at a height such that the average level of the water is 1.10 meters above the generator.  Make sure that the tubing is not sagging below the level of the generator opening.  If it is, move the generator so that the water will flow constantly downward to the generator.  Close the water valve on the hose below the water container.  Pour 150 ml of water into the container.  Click the Start button on the Data Studio software.  Open the valve on the hose to release the water after the software has started recording data.  After all of the water has gone through the turbine, and the generator has stopped turning, click the Stop button on the Data Studio software.  Record the amount of energy measured from the output, and then delete the data set from the screen.  Repeat 6-10 4 more times.  Average the energy output for all 5 runs.  Increase the height of the container by .10 meters and repeat steps 2-11.  Repeat steps 2-12 until you have reached a height of 1.50 meters.
