This looks like good data.

You now need to analyze the data as we did in class. Begin by determining the volume change, exit velocity, PE change and KE change for a single interval of your choice.

Here is the data from the experiement friday.

1st Trial

Your work has been received. Please scroll through the document to see any inserted notes (inserted at the appropriate place in the document, in boldface) and a note at the end. The note at the end of the file will confirm that the file has been reviewed; be sure to read that note. If there is no note at the end, notify the instructor through the Submit Work form, and include the date of the posting to your access page.

Change in X Change in Y

14.7 68.5

2nd Trial

Change in X Change in Y

13.9 110.3

3rd Trial

Change in X Change in Y

14.7 70.1

The intial length of the air in the tube was 9.7cm. The inital length of the air in the tube was 16.2. To get the change in x, I took 16.2-1.5 because that was the change in x for the first trial. I then repeated that for each trial using the changes 1.5, 2.3, and 1.5. (I forgot to put this in my table.)

Each change in y had to have 23 added to it because that was the amount that the water had to travel from out of the bottle to the top of the tube where I was actually measuring from.

Therefore each y actually started out at 45.4, 87.3, and 47.8 respectively.

The procedure was that we had a bottle filled with water and it was sealed. The only exit was the two tubes we were measuring. The y tube went straight up away from the bottle and the x tube went perpendicular to the bottle. Someone would squeeze the bottle while two other people measured the movement of the water from both the x and the y tubes. A harder squeeze would constitute a greater change in x and y. This is because the pressure on the water in the bottle increased. This forced is to go out. "

Good. You need to find the pressure difference between the water surface in the bottle and the top of the supported water column, based on the density of water and the height of teh column.

You also need to find the ratio of the pressures as indicated by the behavior of the air column in the sealed end of the tube.
