In terms of mean velocity , where , Eq. (25) becomes,
                                             (26)
Referring to Eq. (23), the maximum velocity occurs midway between the plate, i.e. at , so that
                              (27)
It may be noted that the flow remains laminar if the Reynolds number remains below 1400. For higher Reynolds number flow, the above analysis will no longer be valid because the flow field becomes complex, three-dimensional and unsteady.
