9.11 viscous fluid flows past a flat plate such that theboundary layer thickness at a distance 1.3 m from the leading edgeis 12 mm. determine the boundary layer thickness at distances of0.20, 2.0, and 20 m from the leading edge. assume laminar flow. (b)if the upstream velocity of the flow in part (a) is u 1.5 m/s,determine the kinematic viscosity of the fluid.
