## Main Question or Discussion Point

I have a small assignment at work that I can't seem to figure out. To not bore you with the details, I have developed a simple scenario.

Say you have water in a tower that is 100ft tall that is flowing through a vertical pipe to the ground. If this pipe is instantaneously closed at the top, at what height would the water equilibrate? and what would be the pressure in inside the pipe between the top of the water and the top of the pipe?

So far, I have developed the simple, atmospheric pressure = (density of water)x(gravity)x(height of water at equilibrium) + (pressure at the top of the pipe)

Obviously, the height of the water can't be greater than 10m because then according to the previous equation, the pressure at the top of the pipe would be negative, right?

Any help would be appreciated,

Vivek
