STEADY, LAMINAR FLOW BETWEEN FIXED PARALLEL PLATES

Consider the flow between two horizontal, infinite parallel plates as shown in Fig. 4(a). For this geometry, the fluid particles move in the x- direction parallel to the plates and there is no velocity in the y and z direction i.e. . So the continuity equation can be written as,

Further, for steady flow,
