Fluid Mechanics

Derive the integral and differential forms of the momentum conservation for a system with constant volume. Explain the assumptions under which you get the Navier-Stokes equations. Assume that you do not know the conservation equations for the general quantity; give all the details. Provide the physical meaning and the units of all the terms appearing in the integral and differential equations.

Keep in mind: Accumulation = Net In by Diffusion + Net In by Convection + Net Production
