(a) As illustrated in Fig. 1a, consider a steady, incompressible. laminar flow (with a
constant viscosity) confined by two infinite parallel plates. One plate is moving at
speed U, while the other plate is held fixed. Assuming that the flow is parallel (y = 0)
and is purely two-dimensional (in x and y direction). The boundary conditions are (1)
at y= 0, น = v=w = 0. (2) at y = Ly, น = U, y=w=0.
Based on the above assumptions, develop the simplified continuity and momentum
equations (please provide reasons for why certain terms can be neglected) (7 points)
