Part b: A flat plate with sharp leading edge is placed in the test section of a low-speed wind tunnel. The working section of the wind tunnel has been designed to produce a region of constant free stream velocity (i.e., for x S 1.0 m, Ue = 27.0 m/s), followed by a region of decelerating flow (i.e., for x > 1.0, Ue = A (1 m/s, Figure Q1. = Lref Wind Tunnel Wall m y Ue = 27.0 for x S 10 m V.-1(1-2) m/s U = A1- m, for x 2 1.0 m For B 1.0 m Flat Plate Figure Q1 3 ve is the freestream air velocity, x is the streamwise position in meter, Lref is a reference length equal to 10 m and x = 0 corresponds to the leading edge of the flat plate. 1- Determine the constant A and its dimension.
