Question:

Prior to take-off the pilot of a 6000-lb twin-engine airplane tests the reversible-pitch propellers by increasing the reverse thrust with the brakes at point B locked. Knowing that point G is the center of gravity of the airplane, determine the velocity of the air in the two 6.6-ft-diameter slipstreams when the nose wheel A begins to lift off the ground. Assume γ = 0.075 lb/ft3 and neglect the approach velocity of the air.
