## Homework Statement

A sealed tank is completely full of water. The water in the tank is stationary. The gauge pressure at the top of the tank is 150 kPa.

A mechanical failure of the tank creates a hole of area 1.00 cm2 at the top of the tank. Water flows out of the hole, rising in a vertical column.

What is the speed of the water as it emerges from the hole?

What is the height of the column of water?

## Homework Equations

P+1/2*rho*v^2+rho*gy=constant

v=(2gh)^1/2

## The Attempt at a Solution

I calculated the abs pressure as 251.3k Pa

But then i don't know how to find the speed without the height of the water?
