A water tank open to the atmosphere gets a leak in it in the form of a circular hole located a height h below the level of the water.

a.

Find an equation for the velocity v of the water going through the hole right when the leak is sprung.

b.

If h=10.0m, what is v?

Assume that the velocity of the water in the tank is so small that it can be approximated by zero.

• Hint:
• Solution: part a.
• Solution: part b.
