Question

For a super soaker water gun, a pump handle is moved back and forth to build up significant pressure in the water reservoir. The water is released by pulling a trigger and shooting the water a significant distance. Assuming that you can create an absolute pressure of 8 atm in the reservoir:

a) What is the velocity at which the water leaves the gun?

b) If the water exits the gun through a hole with a radius of 1-mm, what is the volume

rate of flow in m3/s?

c) If the water gun is fired horizontally and held 1.2 meters above the ground, where

does the water hit the ground?
