Question: Standard air flows over a horizontal smooth flat plate at freestream speed U = 2 0 m / s . The plate length is L

Standard air flows over a horizontal smooth flat plate at freestream speed U=20 m/s. The plate length is L=1.5 m and its width is b=0.8 m. The pressure gradient is zero. The boundary layer is tripped so that it is turbulent from the leading edge; the velocity profile is well represented by the 1/7-power expression.
