The modern Boeing 747 passenger jet airplane cruises at a speed up to 900 km/hr, at an altitude of 11,000 m. The cabin pressure is maintained equivalent to the atmospheric pressure at an altitude of 2,000 m. This is called the "cabin altitude".

The pressure as a function of altitude is obtained via a simple formula that depends on the temperature and a variety of other physical parameters.

Let's assume the area of the passenger windows are about 0.082 m^2.

If the airplane were stationary at its cruising altitude, what would be the force on the window?
