Basic equation applicable = P + 0.5 v^2
a) if both the wings are at same height, the velocity will same resulting in null pressure difference
b) Pbottom - Ptop = 0.5 ( 245^2 - 222^2) = 0.5 ( 1.29 ) ( 60025 - 49284) =6927. 945 Pascals
c) Lift forc e= 6927. 945( 4) =27711.78 N
d) lift is directly proportional to dnsity, mars density is less than earth's so an airplane will experience less lift

An airplane wing generates lift due to a difference in air speed above and below the...
5. (a) (5 pts) The lift of an airplane wing is the difference in pressure above and below the wings times the area of the wing. How much lift is generated by a wing with an area of 16.2 square meters and an average pressure differential of 675 Nim (675 pascals) between the top and bottom of the wing? (b) (5 pts) How much cargo could a plane with this much lift carry if the empty plane has a mass...
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.
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.
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.
PRACTICE IT Use the worked example above to help you solve this problem. An airplane has wings, each with area 4.05 m2, designed so that air flows over the top of the wing at 249 m/s and underneath the wing at 226 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. Your response differs from the correct...
An airplane has an effective wing surface area of 21.9 m2 that is generating the lift force. In level flight the air speed over the top of the wings is 70.0 m/s, while the air speed beneath the wings is 47.0 m/s. What is the weight of the plane?
An airplane wing was designed so that the speed of the air across the wing is 248 m/s when the speed of the air below the wing is 194 m/s. The density of the air is 1.29 kg/m^3. What is the lifting force on a wing of area 23.0 m^2?
An airplane wing is designed so that the speed of the air across the top of the wing is 283 m/s when the speed of the air below the wing is 223 m/s. The density of the air is 1.29 kg/m3. What is the lifting force on a wing of area 22.0 m2?
An air-plane has an effective wing surface area of 12.0 m² that is generating the lift force. In level flight the air speed over the top of the wings is 65.5 m/s, while the air speed beneath the wings is 39.0 m/s. What is the weight of the plane?(The density of air is 1.29 kg/m³)
Approximately what size wings would an aircraft need on Mars if its engine generates the same differences in speed as in the "Practice It" ( wing area: 3.50 m2, air flows over the top of the wing at 246 m/s, air flows underneath the wing at 223 m/s) and the total mass of the craft is 300 kg? The density of air on the surface of Mars is approximately one percent Earth's density at sea level, and the acceleration of...
