6. The wing is part of an airplane that flies at 201 ft/s at sea level and weighs 2800 lbs. Its wing area is 178 square and its span is 30 ft. a What is the wing's aspect ratio? b At what lift coefficient is the aircraft flying at? What is the wing's drag coefficient in this situation? Assume that the wing is the only part of the aircraft providing lift. d What is the Oswald efficiency of this wing? e What is the stall velocity of the wing? If the wing is rectangular, and the critical Reynolds number is 500,000, what is the friction drag coefficient of this wing? 6.
