## Homework Statement

There is a cyllindrical glass (r=0.05 m) full of water. It is rotating around its vertical geometric axis with 3 turns per second. How many centimetres higher is water at the rim than in the centre of the glass . Water rotates together with the glass.

## Homework Equations

p=ρah

ω=2πγ

a=ω

^{2}r

## The Attempt at a Solution

All I know is that the shape of water is parabolic. In the centre there is no additional pressure from rotation, the pressure on the glass is p=ρah, a=ω

^{2}r

total pressure on any point is p

_{x}+ p

_{y}(vectorial sumation)
