The velocity over a flat plate can be approximated by = (2 ), where is the thickness of the viscous layer as shown in the figure below. In reality the thickness of this layer increases in the direction of flow. a. Estimate the viscous shear force due to the water flowing (at = 20) past a flat plate with velocity = 20 m/s by assuming constant thickness of = 5 mm, over a distance = 0.4 m along a plate which is = 0.2 m wide. b. If the total length of the plate is 0.75 m, will the flow at the end of the plate be turbulent or laminar? Explain your
