Problem 6: Consider the incompressible Newtonian pipe flow (Fig. 6). Assume the flow is essentially axial, vz #0 but v = ve = 0 and ô/ôe = 0. The flow is fully developed and steady in a horizontal pipe with %3D the constant pressure gradient. Apply the Navier-Stokes equations and: a) Develop simplified governing equations (continuity and momentum) for this flow; b) Apply the boundary conditions and determine the velocity profile; and c) Develop expressions for the flow rate and mean velocity from the velocity profile.

Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.
