Afinite wing area of 1.5 ft2 and aspect ratio of 6 is tested in a subsonic wind tunnel at a velocity of 180 ft/s at standard sea-level conditions. at an angle of attack of −1°, the measured lift and drag are 0 and 0.181 lb, respectively. at an angle of attack of 2°, the lift and drag are measured as 5.0 and 0.23 lb, respectively. calculate the span efficiency factor and the infinite-wing lift slope.
