Query Introductory Flow Experiment (no summary needed) Is the depth changing at a regular rate, at a faster and faster rate, or at a slower and slower rate? Support your conclusion.

......!!!!!!!!...................................

RESPONSE -->

based on my scetch of the graph i believe that the graph is changing at a regular rate because i believe that the flow of liquid is at its maximum flow and the liquid is coming out as fast as it can

** If you time the water at equal time intervals you should find that the depth changes by less and less with each new interval.

If you timed the depth at equal intervals of depth you should find that each interval takes longer than the one before it.

}

Either way you would conclude that water flows from the hole at a decreasing rate.

The reason is that as the water depth decreases the pressure forcing the water out of the hole decreases. **

this makes sence i guess my graph wasnt exact and when i made my best fit line it wasnt the 'best' fit

What does the graph of depth vs. clock time look like? Is it increasing or decreasing? Does the rate of increase or decrease speed up or slow down? Does your graph intercept the y axis? Does it intercept the x axis? How would you describe its overall shape?

......!!!!!!!!...................................

RESPONSE -->

the graph is a decreasing graph that has a decreasing rate and the graph intercept the y axis when the time is 0 so only when it starts and itll intersect the x axis when the liquid is empty the shape is like half of a sideways perabula

** The graph will start on the positive y axis and will decrease at a decreasing rate.

The shape of the graph is the left-hand side of a parabola that opens upward. The right-hand half of the parabola does not correspond to the flow. The lef-hand half of the parabola, which corresponds to the flow, gets less and less steep with increasing clock time, matching the fact that that the rate of decrease is slowing.

At the instant the containers empties, the water will be at the level of the hole. If depth is measured relative to the hole, then at the instant depth will reach zero. The corresponding graph point will lie on the t axis and will correspond to the vertex of the parabola. **
