A rectangular aerofoil of 100 mm chord and 750 mm span is tested in a wind-tunnel

A rectangular aerofoil of 100 mm chord and 750 mm span is tested in a wind-tunnel. When the air velocity is 30 m ·s−1 and the angle of attack 7◦ the lift and drag are 32.8 N and 1.68 N respectively. Assuming an air density of 1.23 kg · m−3 and an elliptical distribution of lift, calculate the coefficients of lift, drag and vortex drag, the corresponding angle of attack for an aerofoil of the same profile but aspect ratio 5.0, and the lift and drag coefficients at this aspect ratio.
