A. Find the pressure difference on an airplane wing if air flows over the upper surface with a speed of 113m/s, and along the bottom surface with a speed of 104m/s. Delta P= ? kPa
B. If the area of the wing is 33m^2, what is the net upward force exerted on the wing?
-Express your answer using two sig figs. F= ? kN
From bernoulli:
A =33 m^2
p = 1.29 kg/m^3
Vt = 113 m/s
Vb = 104 m/s
?P = (1/2)*?*(Vt^2-Vb^2)
=1259.685Pa
Lift = ?P * A
= 41569.605 N
From bernoulli's P +1/2 rho v^2 = P + 1/2 rho v^2
so dP = 1/2 * 1.225 ( 113^2 - 104^2) = 1196.2 Pa
b) F=PA = 1196.2*33= 39475 N = 39.475 kN

Find the pressure difference on an airplane wing if air flows over the upper surface with a speed of 115 m/s , and along the bottom surface with a speed of 103 m/s . Answer is in kPa. If the area of the wing is 33 m2 , what is the net upward force exerted on the wing? Express your answer using two significant figures. Answer in kN
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...
If the speed of flow past the lower surface of an airplane wing is 101 m/s, what speed of flow over the upper surface will give a pressure difference of 889 Pa between upper and lower surfaces? Take the density of air to be 1.30 × 10-3 g/cm3. Assume the lower surface is at the higher pressure.
An airplane has a mass of 2.1×106 kg , and the air flows past the lower surface of the wings at 96 m/s If the wings have a surface area of 1500 m2 , how fast must the air flow over the upper surface of the wing if the plane is to stay in the air? Express your answer to two significant figures and include the appropriate units.
What is the net upward force on an airplane wing of area 24.9 m2 if the speed of air flow is 250 m/s across the top of the wing and 234 m/s across the bottom? (The density of air where the airplane flies is ρair = 1.16 kg/m3.)
What is the net upward force on an airplane wing of area 27.8 m2 if the speed of air flow is 247 m/s across the top of the wing and 222 m/s across the bottom? (The density of air where the airplane flies is rho_air = 1.13 kg/m^3.)
For an airplane in flight, the average speed of the air relative to the plane is 317 m/s below the wings and 348 m/s above the wings. The bottom of each wing has a surface area of 29.9 m2. Calculate the lift, which is the net upward force of air on the plane.

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.
For an airplane in flight, the average speed of the air relative to the plane is 306 m/s below the wings and 336 m/s above the wings (see the figure below). The bottom of each wing has a surface area of 29.7 m2. Calculate the lift, which is the net upward force of air on the plane.
