A Flying Wing has a swept symmetric airfoil with a planform area of 3700 sq ft, a root cord at the airplane centerline of 34 ft, an overall taper ratio of 0.275, and a span of 170 ft. The average weighted airfoil thickness ratio is 10.2% and the wing has 36 degrees of sweepback at the 25% cord line. The airplane is cruising at M=0.23 with an angle of attack of 5 degrees, at a pressure altitude of 17,000 ft on a standard day, with a wing loading of 105 lbf/sq ft. For these conditions, determine the following:

a) skin friction drag coefficient

b)pressure drag coefficient

c)induced drag coefficient

d)total drag coefficient
