The difference in pressure between the lower and upper surface of air plane?
Correct answer: A. Depends on the angle and orientation of the plane
- A. Depends on the angle and orientation of the plane
- B. Independent of angle and orientation
- C. Insufficient information is provided to determine
- D. All of the above
Explanation
The pressure difference between the lower and upper surfaces of an airplane is influenced by the angle of attack and the airplane's orientation. This is because these factors affect the airflow around the wings, altering the lift generated. Option A is correct as it acknowledges this dependency. Option B is incorrect because the pressure difference is not independent of the airplane's orientation. Option C is also incorrect as the question provides enough context to determine the relationship. Option D is wrong since not all statements can be simultaneously true.

About Fluid Dynamics
Fluid flow is described through speed, pressure and density, including steady flow and the equation of continuity for conserving mass. Bernoulli's equation relates pressure, speed and height, while fluid drag and terminal velocity explain why a falling object eventually moves at constant speed when drag balances its weight.
