"Webbhas a velocity U in its own plane (the other plate is at rest) as a result of the application of a shear stress, τ, and there is no pressure gradient in the ﬂuid. In contrast in planar Poiseuille ﬂow both plates are at rest and the ﬂow is caused by a pressure gradient, dp/dx, in the direction, x, parallel to the plates.
