## Homework Statement

There is a building with 3 floors: ground floor, first floor and second floor. Ground floor is at level zero, first floor is 3 meters above it and second floor is 6 meters above the ground level.

The hydraulic system is made in a way that water barely reaches the second floor.

Now I let water run from a washbasin situated on the ground floor: estimate the speed of the water.

## The Attempt at a Solution

I have too many ideas (which is like having none), so I would prefer someone directing me on the right way :)

Thanks :)
