4. An airplane has a wing area of 428 m2. In flight, the velocity of the air beneath the wing
is 250 m/s and the velocity of air above the wing is 290 m/s. The density of air is 1.20
kg/m3.
a) Determine the upward force on the WING (HINT: use the Bernoulli Equation)
b) Determine the MASS of an airplane that this WING could support in the air
c) Is this WING sufficient to support a Boeing 777 with a fully loaded MASS of
300,000 kg?
