Question

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 < 1.0 m, U̟ = 27.0 m/s), followed by a
region of decelerating flow (i.e., for x 2 1.0, U̟ = A'(1 – m/s, Figure Q1.
