### Aulateórica 11

Rotação do tipocorposólido.

Princípios de Conservação

(massa, momentum e energia)

Rotating Fluid

Rotação do tipocorposólido

Angular velocity:

Aceleration:

Pressure Gradient must balance the inertia force:

Integração da Equação
• Integrating fist in r (in an horizontal plane)
• Differentiating in “z”
• Where p0 is the pressure at the free surface. In fact at r=0 and z=0
The free surface is a parabola
• The position of the free surface can be found using volume conservation or knowing that:
The over-elevation
• Applied to the point located on the glass surface, at the same vertical coordinate as the free surface at the rotation axis gives:
• The over-elevation above the still level is h/2.
