You didn't actually have to do this since you did the other, but since you did I'll be giving you some extra credit for the additional effort.
However it's good to have base data for the graduated cylinder, since we'll be using it again next week or the week after.
Have already performed an experiment similiar to this one.
Decrease.
Remain the same.
Bernoulli's Principle.
A change in velocity implies action of a force as defined by Newton's Laws Of Motion.
Pressure in the action of force.
Changing at a regular rate but its hard to tell.
Decreasing in a linear fashion.
Decrease.
Steady rate.
Decreasing in a linear fashion similiar to the depth verses time graph.

Depth is changing at a slower rate as expected.
Depth is decreasing but not quite in a linear fashion. It appears to be decreasing, concave up.
Obtained velocities by taking the change in distance (from first distance) divided by change in time (from t=0).

Decreasing.
I got the data.
decrease
deacrease
as the pressure of the water decreases the velocity of the water will decrease.the size of the exit hole will determine how fast the water will exit.
as the velocity of the water changes the pressure changes.you can see this by the distance of the stream of water. less preasure = less distance,more pressure = more distance
faster and faster
start out at a gradual incline and then gets steaper and steaper
deacreases
deacreasing
it would start out really fast and then slow down
