A laminar boundary layer of 20-C atmospheric air moving at 2 m=s exists on one side of a 2-m-wide, 3-m-long ?at plate. At x ¼ 3 m ?nd:
(a) The boundary-layer thickness.
(b) The wall shear stress.
(c) The maximum y-component of velocity.
(d) The drag force.
(e) The displacement and momentum thicknesses.
(f) The ?ow rate through the boundary layer.
