Che 311. Can you help me? I will rate your work. Thank you.

3. Without using shell balance, show the complete derivation needed for steady state shape of the free surface of a liquid placed in a container caused to rotate about it own axis at angular velocity, o. Assume that fluid has constant viscosity and constant density. Assume cylinder axis is vertical (a) Write your postulates, assumptions, governing equations and boundary conditions (5+5+5+5) (b) Show the necessary steps needed to get velocity distribution and the equation for the shape of the free surface.
