An airplane weighing 5,000 lb is flying at standard sea levelwith a velocity of 550 mi/h. At this velocity, the L/D ratio is amaximum. The wing area and aspect ratio are 200 ft2 and8.5, respectively. The Oswald efficiency factor is 0.93. Calculatethe total drag on the airplane. Assume ?? = 0.002377slug/ft3. (Round the final answer to one decimalplace.)
The total drag on the airplane is _______lb.
