How does the system behave and how does it 'feel'?
The air in the pressure tube changes a little bit and water is continuing to flow out of the vertical tube.
Length of the air column in units of your measuring device:
Your report of the vertical position of the first mark relative to the water surface of the first mark, the length of the air column in units of your selected measuring device, and the two meniscus positions observed with each of your five trials.

Your data look good. I'll look forward to getting your work on Part 2 of this experiment.
