Problem
A cylindrical bucket of inner radius 12cm contains water and is spun steadily about its vertical axis at 1.5 revolutions per second. The water has been turning long enough to rotate with the bucket as a rigid body; it is incompressible and inviscid, and the air above the free surface is at atmospheric pressure. Take g=9.8ms−2. How high above the lowest point of the free surface (the vertex on the axis) does the surface stand at the wall?
