A Boeing-737 airliner has a mass of 20 500 kg.The total area of the wings is 100 m².What must be the pressure difference between the top and bottom of the wings to keep the airplane up?

Question

Quizplus · Accepted Answer

The pressure difference required to keep the airplane up can be calculated using the lift equation: Lift = Pressure difference * Wing area. The lift must equal the weight of the airplane, which is mass * gravity (20,500 kg * 9.81 m/s²). Solving for pressure difference gives approximately 2,009 Pa.
