if a tube is filled with water and a small hole is made....what forces account for the rate at which the water exits the tube? thanx for any help!

The height of the column of water above the hole will determine the pressure. The force responsible is hydraulic pressure caused by gravity. The size of the hole will determine the escapement volume, or the amount of time required to empty the tube. As the column of water falls the pressure of the stream exiting through the hole decreases.
