To model the velocity distribution in the curved inlet section of a wind tunnel, the radius of curvature of the streamlines is expressed as R=LR0/2n. As a first approximation assume the air speed along each streamline is V=20 m/s. Evaluate the pressure change from n=0 to the tunnel wall at n=L/2, if L=150 mm and R0=0.6 m.
