Force through absolute Pressure

AI Thread Summary
To calculate the force on the airplane door, first determine the pressure difference between the inside and outside of the plane. The inside pressure is 14 psia, and the outside pressure at altitude is 2 psia, resulting in a pressure difference of 12 psia. The force can be calculated using the formula: Force = Pressure Difference x Area. Substituting the values gives: Force = 12 psia x 4032 in², which equals 48,384 pounds. Understanding the relationship between pressure and force is crucial for solving this problem effectively.

If an airplane door has an area of 4032 in^2 and the pressure inside the plane is 14 psia (absolute), What is the force on the door when the plane flies at an altitude where the pressure is 2 psia?
