Air at 20°C flows at V = 8.5 m/s parallel to a flat plate (Fig. P10–94). The front of the plate is well rounded, and the plate is 40 cm long. The plate thickness is h = 0.75 cm, but because of boundary layer displacement effects, the flow outside the boundary layer “sees” a plate that has larger apparent thickness. Calculate the apparent thickness of the plate (include both sides) at downstream distance x = 10 cm.
