Pressure Dependent on Depth

2B20.15

Materials: 2 Liter Bottle with 3 Pin Holes, Water

A two liter bottle is fashioned to have three pinholes at different heights on the bottle. Since the pressure is different at the various pin locations, the exit velocity of the water will be different at these locations. The highest pin has the lowest pressure, and thus will have the smallest exit velocity while the pin on the bottom has the greatest pressure and thus the exit velocity of the water will be the greatest.
