The area of the wings of the plane, A = 2 × 25 = 50 m2
Speed of air over the lower wing, V1 = 180 km/h = 50 m/s Speed of air over the upper
wing, V2 = 234 km/h = 65 m/s
The upward force on the plane can be obtained using Bernoulli’s equation as:
The upward force (F) on the plane can be calculated as:
(P1 - P2)A
Using Newton’s force equation, we can obtain the mass (m) of the plane as:
