Question

Equation of Continuity and Bernoulli’s Equation. Air flow horizontally past a small airplane’s wings such that the speed is 70.0 m/s over the top surface and 60.0 m/s past the bottom surface. The plane has a mass of 1,340 kg and a wing area of 16.2 m². The density of air is p_air = 1.20 kg/m³.

a. What is the weight of the airplane?

b. What is the pressure difference between the lower and upper wings (ignore the gravitational potential energy terms)?

c. What Lift is produced by the wings?

d. What is the net vertical force on the airplane?
