decrease per the decrease in pressure
decrease
the velocity of the water surface and the exiting water increase as the diameter of the hole increases and the diameter of the cylinder decreases.
no velocity change is possible without the action of a force
slower and slower
it would curve showing a depth decreasing slower as time becomes longer
decrease
decreasing
a curve showing how as time grows larger horizontal distance diminishes faster and faster

slower and slower
as clock time increases the water depth decreases more rapidly at first and slower as time goes on
velocity = distance/time (cm/sec)

velocity rises to its peak at 1.088 quickly then declines as time progresses
I made a formula in Excel to divide change in velocity by change in time for each time interval.

the data indicates that the acceleration of the water increases up from 0 to a maximum value of 0.69632 then decreases for the rest of the experiment.
I think the acceleration of the water is actually decreasing after its initial climb, because of the decreased flow rate caused by the lower pressure.
Your work on this experiment will be compiled and you will receive a more extensive analysis and a reply after the due date. I see no obvious problem with the results you have submitted.
