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...

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.

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?

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.

(20%) Problem 5: A frequently quoted rule of thumb in aircraft design is that wings should produce about 1000 N of lift per square meter of wing.

A U-tube contains liquid of unknown density. An oil of density
770 kg/m³ is poured into one arm of the tube until the oil column
is 13.5 cm high. The oil-air interface is then 4.5 cm above the
liquid level in the other arm of the U-tube. Find the density of
the liquid.
