Problem 3: Consider incompressible Newtonian fluid flow between parallel plates (Fig. 4) that are horizontal and a distance h apart. The plates can be considered as very wide and very long so that the flow is essentially axial; hence, u ‡ 0 but v = w = 0 and a/az-0. B represents the plate width. The flow is fully developed laminar and steady.

Consider incompressible Newtonian fluid flow between parallel plates (Fig. 4) that are horizontal and a distance h  apart. The plates can be considered as very wide and very long so that the flow is essentially axial; hence, u ≠ 0 but v = w = 0 and ∂/∂z=0. B represents the plate width. The flow is fully developed laminar and steady.

between parallel plates (Fig. 4) that are horizontal and a distance h
apart. The plates can be considered as very wide and very long so
that the flow is essentially axial; hence, u ‡ 0 but v = w = 0 and
a/az-0. B represents the plate width. The flow is fully developed
laminar and steady.
a) Simplify the governing equations (continuity and
momentum) for this flow;
