For an airplane in flight, the average speed of the air relative to the plane is 320 m/s below the wings and 352 m/s above the wings (see the figure below). The bottom of each wing has a surface area of 30.9 m2. Calculate the lift, which is the net upward force of air on the plane.
Homework Answers
BY applying bernoullis equation between the upper and lower
point
P1/p + V12 /2 + gH1 =
P2/p + V22/2 +
gH2
Neglecting H term because approx same
(P1 - P2) = p(V22 -
V12 )/2
Where p is density of air taking as p = 1.2 kg/m3
(P1 - P2) = 1.2*(3522 -
3202)/2 = 12.902 kPa
Force = Pressure*area
Therefore Lift force = 12.902*30.9 = 398.68 kN

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.
