The goal of this experiment is to see if the water level in a can affects the time it takes the water to flow from a hole in the bottom of a can. In order to perform this experiment I made a chart with the following categories: Seconds, Experimental Height and Theoretical Height. Then I nailed a hole in the bottom of a coffee can and filled it with water while I covered the bottom of the hole with my finger. I then put a ruler in the can and measured the initial height of the water in millimeters and recorded the data. I uncovered the hole and after ten seconds recovered it. Then re measured the new height of the remaining water. I repeated this till the water was almost gone. After the water can was empty I measured the diameter of the bottom of the can and the diameter of the hole. I substituted my data into the formula (vh / o ??“ 70d ? /D ? t) ?. h/o is the initial height of the water which is 90 mm. D is the diameter of the can which is 98 mm. and d is the diameter hole which 5 mm. t changes each time the equation is done because it stands for time. The differences between the theoretical and the experimental height could be how high the can was held, the diameter of the hole, the time between each entry. It was difficult get precise measurements because I couldn ??™ t tell exactly where the meniscus was. Next time it might benefit me to use a graduated cylinder or a clear container instead of a coffee can.
