Purpose : to determine experimentally the relationship between the rate of flow of water through a narrow opening and the height of the water column.

any ideas in how i could do this experiment and what kind of data to use etc. and how this can conclude to a design in an hydro electric dam.

experiment is used with a 50 mL burette (tube with narrow opening) , stop watch, ruler, and beakers.

thanks :D

Ask yourself the following questions:

1. what do I need to produce a column of water? Will it be big enough to give me a measureable volume of water flowing out the opening without changing the height significantly?

2. how do I measure the volume of water that escapes?

3. How do I measure the time it takes to escape so I can determine the volume/unit time?

4. How do I measure the area of the opening? How do I calculate the flow rate from that data and the area of the opening?

If you think about all these things carefully, you will be on the road to a successful experiment.
