A small jet airplane has a total wing area of 62.5 m2 and a mass of 7.03 104 kg. (a) If this jet is in horizontal flight, determine the pressure difference between the lower and upper surfaces of the wings. (b) When the speed of air traveling over the wing is 237 m/s, determine the speed of air under the wing. Use 1.29 kg/m3 as the density of air.

An airplane wing generates lift due to a difference in air speed above and below the wing. If the wings are both at the same height, what term is the same on both sides of the Bernoulli equation? Calculate the change in pressure (P-bottom - P_top) a wing experiences if the air moves at 245 m/s above the wing and 222m/s below the wing. The density of air is 1.29kg/m^3. Calculate the lift force the plane experiences if it has...

Use the worked example above to help you solve this problem. An airplane has wings, each with area 3.95 m2, designed so that air flows over the top of the wing at 249 m/s and underneath the wing at 225 m/s. Find the mass of the airplane such that the lift on the plane will support its weight, assuming the force from the pressure difference across the wings is directed straight upwards.
