Question

An airplane has a mats of 28×10⁶ kg, and tho air flows past the iower surtace of the wings at 83nn/s. It the wings have a surtace area of 1500 m² , how tast mut the air fow over the Lpper aurface of the wing the the plane ia se tay in hat air?

Answer 1

Physics concepts, including Bernoulli's principle and the lift equation, are used to calculate the necessary airspeed over an airplane's wing to provide the required lift force, given a standard lift per wing area, airspeed under the wing, and air density.

Step-by-step explanation:

The question involves principles of physics, particularly fluid dynamics and Bernoulli's principle, which relates to aircraft and their lift mechanism. To find out how fast the air must move over the upper surface to create the ideal lift for an airplane, we use a rule of thumb in aircraft design that suggests wings should produce about 1000 N of lift per square meter of wing. Considering the aircraft has a ground speed of 60.0 m/s, with air flowing beneath the wing at the same speed, and the air density at sea level is 1.29 kg/m³, we can apply Bernoulli's equation to find the required speed for the air moving over the upper surface of the wing. Additionally, the lift equation could be used, which relates lift force to the air density, velocity, surface area, and lift coefficient.
