Suppose the air outside the window moves with a speed of approximately 160 m/sm/s shortly after takeoff, and that the air inside the plane is at atmospheric pressure. If the window is 28 cmcm by 40 cmcm , find the force exerted on the window by air pressure? Part A Find the pressure difference between the inside and outside of the window.
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.

On a vacation flight, you look out the window of the jet and wonder about the forces exerted on the window. Suppose the air outside the window moves with a speed of approximately 160 m/sm/s shortly after takeoff, and that the air inside the plane is at atmospheric pressure.
If the window is 28 cmcm by 40 cmcm , find the force exerted on the window by air pressure?
